1) Measurement Using the Measuring Voltage Output without
Interruption
This is a basic and practical measuring method.
Note: With this measuring method, the red measuring rod tip carries the
measuring voltage without interruption. This can cause an electrical
shock if the operator handles the measuring rods without care.
(1) Set the RANGE and VOLTAGE selectors according to your measurement
program. Set the MEASURE/CHARGE/DISCHARGE function selector to
theMEASURE position. In this status, the meter outputs the selected
measuring voltage, making a measurement possible.
(2) Measure the sample by touching the tips of the measuring rods to the part
to be measured.
(3) If necessary, change the RANGE selector setting to optimize the reading
on the indicating meter.
(4) When the measurement is completed, set the function selector to the
DISCHARGE position. Again, touch the measuring rod to the measured
part of the sample to discharge the charge , and disarm the sample.
2) Measurement Using the Charge Function
This is a convenient method to measure a number of similar samples
without changing the RANGE selector setting.
(1) Set the RANGE and VOLTAGE selectors according to your measurement
program. Set the MEASURE/CHARGE/DISCHARGE function selector to
the DIS- CHARGE position. Connect the measuring rods to the sample.
(2)
Set the function selector to the CHARGE position to apply the measuring
voltage to the sample. The sample will be charged across an internal
impedance of approx. 30 k
Ω
.
(3) When the charge is completed, set the selector to the MEASURE position.
(4) After completion of the measurement, set the function selector to the
DISCHARGE position to discharge and disarm the sample.
3) Measurement by changing the RANGE Selector Position
This is a modification of the method described in 2) Measurement Using
the Charge Function to accelerate the stability of the resultant reading.
(1) Set the VOLTAGE selector according to your measurement program.
Set the MEASUE/CHRAGE/DISCHARGE function selector to the
DISCHARGE position. Connect the measuring rods to the sample.
Set the RANGE selector to the
×
1 or
×
10 position. Set the function
selector to the MEASURE position to start the measurement.
(2) When the meter needle raises and as it will approach the
∞
mark on
the right most of the meter scale, turn the RANGE selector clockwise
to optimize the reading on the meter scale.
