TEST
If the resistance of the device is below 40 Ω, there
is a continuity beep tone.
If the resistance of the device is more than 40 Ω,
there is no beep tone.
This is useful for checking wiring connections and
operation of switches.
CAUTION
Turn off power and discharge all capacitors on
circuit to be tested before attempting incircuit
resistance measurements.
Accurate measurement is not possible if
external or residual voltage is present.
INSULATION TEST
CAUTION
Turn off power and discharge all capacitors on circuit to be
tested before attempting Insulation test.
Insert test leads into V and COM input terminals.
Set the rotary selector to the desired test voltage position.
Connect the lead probes to the circuit under test.
The display shows
until you press
and a valid
insulation resistance reading is obtained.
Press and hold
TEST
button to start the test.
The LCD shows
(high voltage warning) symbol along with
the resistance in MΩ or GΩ .
The
symbol will be displayed on the LCD until the
TEST
button is released. The meter displays
symbol along
with the maximum resistance for the range when the resistance
is higher than the maximum display range.
NOTE :
When the
button is pressed before the
TEST
button, the test remains active until the
button is pressed again.
LOCK
Release the
button before disconnecting the probes
from the circuit under test. Then, the circuit will automatically be
discharged through the meter.
