Insulation Measurement - AEMC 6536 User Manual

In the MΩ VAR setting, the
(>25V) and that insulation measurements are prohibited.
If the voltage is >15V, continuity and resistance measurements are prohibited.

2.2.2 insulation Measurement

Insulation measurement results can be affected by the impedances of
additional circuits connected in parallel or by transient currents.
Do not start any measurement while the symbol
1. Set the rotary switch to the MΩ VAR position.
2. The instrument displays the configured test voltage. To modify this
setting, press the ► key to enter edit mode (The first digit of the voltage
setting blinks). You can change this by pressing the ▲ key. Then use the
► and ▲ keys to navigate to and change the remaining digits. Allowable
test voltages are 10 through 100V. When finished, press ► to validate
the change.
3. Use the leads to connect the system to be tested to the instrument's
terminals. The system under test must be powered down and
discharged. When testing insulation, the typical connection is negative
(black) lead to conductor and positive (red) lead to ground or the outer
insulation of the device under test.
