Instruction manual digital torque tester

Thank you for purchasing the digital torque measuring device from SAUTER. We hope

that you will be very satisfied with the high quality of the hardness tester and its

extensive functionality. Although the device is a complex and technically advanced

measuring instrument, it is designed for many years of trouble-free use, provided that

it is used for its intended purpose and properly maintained. Before using the instrument

for the first time, please read this operating manual carefully and ensure that it is

always kept within easy reach during use. For any questions, requests and

suggestions, please contact our customer service department at the telephone number

provided.

1 Before commissioning

Before putting the device into operation, check the delivery for any transport damage

to the packaging, the plastic case and the device itself. Should this be the case,

SAUTER must be contacted immediately.

2 General operating information

Functions of the digital torque measuring instrument that are used most frequently (i.e.

display of the torque value, peak hold function, zeroing and changing the displayed

unit) can be called up by pressing a corresponding button on the front panel (see

paragraph Basic functions of the measuring instrument). The setting of the measuring

instrument is done with the menu key (see paragraph Main menu).

3 Initial commissioning

The SAUTER DA digital torque measuring instrument is equipped with a battery set

consisting of 4 rechargeable NiMH AAA batteries. To be on the safe side, the

rechargeable batteries are completely discharged for transport and separated from the

power supply. Insert batteries before using the unit for the first time. To achieve

maximum battery life, recharge the batteries for at least 14-16 hours using the mains

adapter supplied.

6 Operation of the torque measuring instrument DA

6.1 Before commissioning

Insert the four rubberised bottle holders into the openings provided for this purpose,

adjusting their arrangement to the diameter of the bottle or glass. Ensure that the

rubberised bottle holders are inserted as far as they will go and that they are locked on

the keyway. The rubberised holders must not twist after the test sample has been

inserted. The rubber coating ensures a better adhesion of the inserted test sample,

e.g. a bottle, to the measuring instrument. It must be ensured that the measuring plate

is neither loaded nor exposed to the action of any other force when the instrument is

switched on.

6.2 Switching on the device

There are 8 keys arranged on the control panel.

To switch on the device, press the ON/OFF button. A brief autotest will then be

performed, during which the display will show the permissible load value in Newtons.

As soon as the autotest is performed, zero values are displayed, provided that the

measuring plate is unloaded. This is because the meter is automatically zeroed during

the autotest procedure.

Please do not overload the load sensor! Risk of irreparable damage! If the torque

value exceeds 120% of the full scale range, an acoustic signal is triggered and the

symbol OL (eng. overload) appears on the display. If this is the case, remove the test

load and then press the RESET key.

Pressing the ON/OFF key switches the unit off.

When switching off, all current settings are saved, so that the same operating mode is

selected when switching on again.

6.3 Basic functions of the device

The torque gauge can display the torque value for both clockwise (clock-wise, CW,

symbol: ) and counter-clockwise (CCW, symbol: ) operation.

The load indicator bar of the rotation is used to display the load to which the load sensor

is exposed.

When turning clockwise (CW), the load indicator bar moves from right to left. When

turning counterclockwise (CCW), the load indicator bar moves from left to right.

Zeroing the display

During operation it is often necessary to zero the display so that the values already

displayed are not taken into account in the next measurement. To do this, press and

then release the ZERO button.

Changing the measuring unit

Depending on the permissible load of the measuring instrument used, the following

measuring units are available: N-m, kgf-cm, kgf-m, in-lbf, ft-lbf.

To change the measuring unit, press the UNITS key. Each time this key is pressed

again, another measuring unit is displayed until the originally set measuring unit is

displayed. During the selection process, the measurement results are automatically

converted.

Important! It must be remembered that not all units of measurement are always

available. This depends on the permissible load of the respective instrument.

DA-BA-e-2020 7

Changing the measuring mode

The following measuring functions are available: Track, First Peak-Torque and Peak-

Torque.

The measuring function is changed by pressing the MODE button. Pressing this key

again selects the following measuring function until the originally set function is

displayed.

Track function

Press and hold the MODE button until the displayshows the name of the measurement

function "Track". The torque value for the rotation detected by the load sensor is

displayed. The measurement results are displayed continuously:

first peak torque function

Press and hold the MODE key until the display shows the designation of the measuring

function "F-Peak". The first torque peak value is displayed:

Symbol of the

First Peak Torque Function

Peak torque function

Press and hold the MODE key until the display shows the name of the measurement

function "Peak". The highest measured torque value is displayed:

Symbol of the

Peak torque function

Resetting the device

Stored peak values of both types are deleted with the RESET button. This also enables

the acquisition of further peak values.

8 DA-BA-e-2020

Display backlight

By pressing any key, the backlight of the display switches on for 60s. The same applies

if the torque value detected by the load sensor will be higher than 0.5% of the full scale

range.

Saving measured values

Measured values can be saved at any time. To do this, press the MEM/ENTER key.

The memory capacity allows you to store up to 500 measurement results, including

measurement units.

Output signal

The measurement result obtained can be transferred to the PC. It is done by pressing

the PRINT key or by interrogating the instrument from the PC. The respective

command can be sent via RS232 or USB.

6.4 Main menu

Pressing the MENU/ESC key calls up the "Main Menu" screen. The arrow keys UP or

DOWN are used to select desired positions in the mask. Pressing the ENTER key

selects the desired sub-menu, then calls up the desired function and then enters the

respective value. The arrow keys UP, DOWN, LEFT and RIGHT are also used to

change numerical values. Pressing the ESC key returns to the main menu screen.

key. The AUTO-OFF menu mask appears on the display. Press the ESC key to return

to the main menu screen.

The AUTO-OFF function helps to extend the battery life. It can be used to set the time

after which the device should be switched off after the last operating activity (setting

values: Off, 5, 10 and 15 min). If this function is activated, the symbol AO appears in

the main menu mask.

PASS-FAIL

This function is used to set the permissible torque range.Thus, the upper and the lower

limit value of the torque range are determined. If the torque value falls within the

defined range, the displayshows the message PASS (OK). If the torque value detected

is outside the specified range (above or below the range), the display shows FAIL

(NOK). When the PASS-FAIL function is active, the display shows the symbol.

To call up the PASS-FAIL menu screen, position the cursor on the PASS-FAIL function

using the UP or DOWN arrow keys, then press the ENTER key. The display shows the

PASS-FAIL function screen. Press the ESC key to return to the main menu screen.

PASS FAIL MENU

UPPER = 2. 5 N.m

LOWER = 1.0 N.m

Press 'Zero' key to

Clear both values.

Use the LEFT arrow key to position the cursor on the selected value. Set the desired

value with the UP or DOWN arrow keys. Press and hold the key to scroll the list. Select

the desired measuring unit with the RIGHT key. Press the ENTER key to save the

setting made and return to the main menu screen.

The PASS-FAIL function is automatically turned off when the setting of the lower limit

(LOWER) and upper limit (UPPER) is 0 N.

The LOWER value must be lower than the UPPER value.

PASS FAIL MENU

UPPER LIMIT = 2. 5 N.m

LOWER LIMIT = 1.0 N.m

Press the 'Zero' key,

to delete both values.
