3.2. Rare panel of meter

There are four sockets on rare panel of meter:

1. mini USB interface

2. socket for conductive measurement electrode

3. socket for ion selective electrode

4. socket for DO measurement electrode (or

temperature measurement electrode)

3.3. Keypad

3.3.1. Key function

The meter has six keys: F1, F2, F3, ENTER/MENU, CANCEL and ON/OFF/BKLIGHT keys.

In which:

a).F1/F2/F3 key:

The function is not fixed. In each mode, the actual function is in correspondence to the indication

on top of the key.

For example, in starting state as left chart, the lower part of the screen displays ‘START’,

‘MEASURE’, it means F1 is in correspondence to ‘START’. If you press this key, you can start

several functions under starting state including set measurement mode, view measurement

parameter, view stored data, etc...

On upper side of F2 is empty which means F2 key is

invalid.

F3 key is in correspondence to ‘MEASURE’ and you can

start to measure by pressing F3.

INE-DZB-712 Portable Multi-parameter Analyzer

b). ENTER/MENU key: Double function key with different function in each mode. Generally

‘ENTER’ is the first function and ‘MENU’ is the second.

c). CANCEL key: to quit from measurement state or to give up present setting.

d). ON/OFF/BKLIGHT key: to turn on/off meter and the control key of backlight. Under off state,

press this key, you can turn on the meter to start normal operation. When meter is turned on,

press this key, you can turn on the backlight, press again to turn off backlight. When operation

finishes, press this key for more than 4 seconds to turn off the meter.

Meter has automatic turn off function, if no key pressed within the setting time, meter will

be off automatically.

Meter has backlight time control function, user can set by himself.

Note:

Meter has power management technology, when backlight is on, meter will consume about

more 10mA current than backlight is off. In order to save power dissipation, we suggest

using back light as less as possible. After you turn on backlight to view data, try to turn off

backlight timely.

3.3.2. Key Operation

The instrument is portable meter which requires not only beautiful, good looking but also useful

and convenient. So we reduce the key number to 6 and design the operating interface considerably

to limit the amount of pressing which can ensure fast and conveniently using of the meter. Please

see following example:

Example 1: Unit name: Setup measurement mode

Meter allows several measurement modes to measure different measurement parameter, so the

operation of setting measurement mode is comparatively complicated.

In starting state, press F1 (or ENTER/MENU) and then press ‘ENTER/MENU’ key to enter into

setting measurement mode, please refer to the chart.

On left side is list of measurement parameter,

On right side is list of measurement mode,

‘←→’ is on upper side of F1; ‘↑↓’ is on upper side of F2

“CLEAE” or “SELECT” is on upper side of F3.

If you press F1, or F2, you can move cursor up/down or right/left. The function of F3 will change

automatically when cursor is moved

‘√’means the selected measurement parameter or measurement mode: reversed display means cursor

position.

When cursor is moved to a certain item, function of F3 will change automatically, you can press F3

to make a selection or to clear a selection.

INE-DZB-712 Portable Multi-parameter Analyzer

Meter can mostly measure 3 main parameters simultaneously. When you finish selection, press

‘ENTER/MENU ’ key, meter will save the setting and return to starting state, press ‘CANCEL’ key

meter will quit from the operation and return to starting state directly.

Example 2: Unit name: Data input

In many cases, you need to set necessary parameter. Meter has an effective data input method in

the condition of only five keys in using. In order to let user familiar with this data input method,

meter has only way of parameter setting which is displayed as the diag.

On the top is required parameter name.

On upper side is present data input area that black cursor

is flashing.

On left lower side is a little figure keypad

On right lower side is a reflection area of present key

position.

At the bottom are the pressing keys, you can move

up/down, right/left by pressing ‘F1’ and ‘F2’.

At the same time the indication on top of ‘F3’ will automatically follow up and change. When you

input any figure, the ‘-’ on keypad will be automatically amended to ‘C’ which means you can clear

previous input, in case you move keypad to this point and press ‘F3’ (at this time the indication of

‘INPUT’ will be changed to ‘CLEAR’), you can delete all of previous input and re-input. If there is

any mistake, you can amend according to this.

Ex: input data 12.6

Operation step:

a). Firstly，on top of ‘F3’ will be number ‘1’,

press F3 directly, input digit ‘1’

b). Press F1 when top of ‘F3’ number is‘2’,

press F3 input digit ‘2’

c). Press F1 twice when top of ‘F3’ number is ‘.’ ,

press F3 input digit ‘.’

INE-DZB-712 Portable Multi-parameter Analyzer

d). Press F1 three times and F2 once,

when top of ‘F3’ number is ‘6’, press F3 input digit ‘6’

e). Press ENTER/MENU to finish data input of ’12.6’

Note:

For all the operating instructions below, the operation of function key in correspondence

to F1, F2 and F3 will be operated according to indication and not be operated according

to actual pressing key. For example, ‘presently press F3 to start measurement’ will be

amended to ‘presently press START key to start measurement’.
