OPERATING MANUAL

1. Introduction

1.1. General

1.1.1. The present Operating manual is designed for the user coming in contact with resistance

meter А-760 (further – unit).

1.1.2. The Operating manual contains important information about the unit and operating

instructions.

1.1.3. There can be some small variations which are not mentioned in the present Operating

manual due to the constant work on improving reliability and operating characteristics of

the unit.

1.2. Description

1.2.1. The present unit, produced by Armeka Engineering, is used for measuring the resistance

of worksurfaces and flooring and is in accordance with ESD Association standards S4.1

(worksurface – resistance measurements) and S7.1 (Resistive Characterization of

Materials–Floor Materials).

1.2.2. The unit is easy to use and of high operating reliability.

1.3. Specific features

1.3.1. Unlike the competitive products, the present unit provides strict concordance to the

standards. The user gets the result, which allows valuing the quality of ESD safe

equipment and deviations from the standard. It saves the time and improves the quality

of testing.

1.3.2. The unit provides measurement of resistance at two voltages, which allows to measure

resistance from 1000 ohm to 100 Gohm.

1.3.3. Low resistance measurements allow high accuracy control of electrodes. This increases

the reliability of measurements.

1.3.4. Unique circuit allows voltage on electrodes not less than 100 V when measuring

resistance from maximum to 1 mega-ohm and to decrease the lower level of resistance.

1.3.5. Low power consumption allows using only standard low voltage batteries.

1.3.6. The unit is performed in two models “STANDARD” and “EXPERT”. The main

difference is in the construction of electrodes (the construction of electrodes in model

“EXPERT” is several times lighter).

Allows adjusting the initial position of the hand before switching on.

Working position of the unit - horizontal.

4. Preparation work

4.1. General instructions

Read carefully about each operating element before putting the unit into operation.

Understanding how the unit works will help to avoid unnecessary mistakes and prolong service

life of the unit. The unit has 4 test modes allowing measuring of surface resistance, checking

operating capacity and controlling the condition of electrical characteristics of test electrodes

and connection cables at two different test voltages.

4.2. Working conditions

Working temperature ranges from 0 to 40 Сat relative humidity not more than 75% at

30 С. The unit can be damaged if the values are beyond these limits. The unit shouldn’t be used

in environments with strong electric and magnetic fields. These fields can distort measuring

accuracy.

4.3. Unpacking the unit

Check the packing case for possible damage. In case of possible damage, open the case

and check the unit and accessories. Contact your supplier and forwarder if damages found.

If you consider the unit not to have any damages, read carefully the present manual. Check

•move away the cover from the battery compartment;

•put battery «ААА» in the compartment and connect battery «Кrona» to the socket and place

it and the cables into the compartment so that you can easily place back the cover;

•place back the cover.

4.5. Checking and controlling the initial position of the indicator hand

Operating manual

Place the unit on a horizontal surface. Make sure that the switch button is in the position

«Off». The hand of the unit should point at «∞». If it’s the other way, adjust the position of the

hand with the help of adjusting screw» (fig. 2).

5.1. Checking operating capacity of the unit.

Put the switch button in the position «On», press and hold the button “Battery test”,

which is in the middle. The indicator hand should be in the green zone of the lower scale

“Battery test”.

If the hand during the test is in the yellow zone which is to the left of the green zone in the

lower scale, the batteries should be replaced. If it’s to the right of the green zone, the unit

should be sent to the service center.

ATTENTION

The unit switches on and power supply starts when the switch button is in the

position «On». Don’t forget to put the button into the position «Off» when the measurements

are fulfilled.

5.2. Checking test electrodes and connecting cables

•put the electrodes on a flat surface as it’s shown on fig. 3 and hold the upper electrode by the

handle (model “STANDARD”);

•put the electrodes on a flat surface as it’s shown on fig. 4 and press the upper electrode so

that the free parts sink in the frame. (model “EXPERT”);

•connect the electrodes to input sockets with the help of connecting cables;

•put switch button in the position «On»;

•press the button «Test Continuity / 10V»;

The indicator hand should be in the green field of the middle scale.
