The Multifunction Tester has the features of the Insulation Tester plus the
MOV and GAS Arrester Test.
To access the MOV test, You need the depress the 1000V and
500V keys Simultaneously And To access the GAS
Arrester Test, you need to depress the 250V and Ohm Key
simultaneously.
The Multifunction Tester has
everything
You'll ever Want from an
electrical
Test and Measuring tool.
Before any test is performed, (provided
the test leads are connected properly and
the fuse is intact) it make a voltage test to
assert that there is no voltage on the device or
circuit under test.
If there is a voltage which could be a problem for the test, the tester,
automatically, switch to the Voltmeter and shows the voltage on the display.
Be it AC or DC.
If voltage is present on the leads before test is started, the selected test is
cancelled and the keypad is disabled, preventing errors of operation. This
makes this tester one of the safest to operate to date.
Once any voltage is cleared, test can begin. Should you want to measure
Insulation Resistance, you can select by using the 250V, 500V and the 1kV
test Voltage which all go into the Giga-Ohm range. Should you want to test
continuity, use the Low ohms scale, down to 0.01Ohm and also the buzzer.
You can null the fuse and test leads using the Auto-Null feature. Of Course
on this model, Auto-hold is featured. You will appreciate the superior Safety
of Auto-Hold when you decide to visually look after your arms and fingers
without needing to check the display. Auto-Hold is always turned ON and
with it, you can simply touch the voltage and remove the test probes. The
last valid voltage will be on the display when you want to see it.
While Dangerous voltages are present on the leads, it beep too, signalling
the user that he is touching dangerous voltage.
