12707 Resistivity Chamber for Liquid Sample Operation Manual

3.5  Measurement

 

3.5 Measurement 

Perform measurement in accordance with the operation manual of each measuring instrument. 

In insulation resistance measurement, VSIM (voltage source current measurement) is generally 

conducted to obtain the resistance value by R=V/I. 

Resistance values can be read directly on the 8340A and the 8252. However, on other electro-

meters, resistance values need to be converted from measured values. 

3.5.1 Setting 

the 

8340A 

Procedure: 

(1)

 

Set the IM/RM switch to RM. 

(2)

 

Press the V SOURCE SET key to set the applied voltage. 

(3)

 

Pressing the OPERATE key will apply the setting voltage. 

(4)

 

Pressing the MEASURE key will start measurement. Discharge or charge the sample if 

necessary. 

3.5.2 Setting 

the 

8240 

Procedure: 

(1)

 

Turn the D GUARD to ON. 

(2)

 

Set the function to A DC (DC current measurement). 

(3)

 

Set the voltage source to OPERATE to apply the setting voltage. 

(4)

 

To charge the sample, apply the setting voltage in the 20 mA range. 

The input resistance is approximately 30 

 at this time. 

(5)

 

To discharge the sample, set the setting voltage to 0 V in the 20 mA range.
