4. The test is completed by letting go of the TEST button or
pushing down the TEST button if in the LOCK mode.
This will shut off the high-voltage. The test resistance
value will be shown in the primary display and held. The
secondary display will show the insulation voltage
remaining in the circuit.
5. The instrument will discharge the balance of the test
voltage automatically through the inner switch of the
meter.
6. Turning the rotary function switch will automatically exit
from a testing status.
Low Resistance (Continuity) Measurements
1. Set the range switch to 400
Ω
/BZ position.
2. Connect the red test lead to the V
Ω
terminal and black to
the COM terminal.
3. Connect the tips of the test leads to both ends of the
circuit under test. Read the resistance in
Ω
on the LCD.
The two ranges (40.00 M
Ω
/400.0 M
Ω
) can be switched
automatically; the resistance in
Ω
flashes in the primary
display and also shows on the analog bar.
4. An impedance on circuit below approximately
≤
35
Ω
,
will be indicated by a continuous beep.
5. The test current of a test resistance at 0
Ω
is 200 to
220 mA.
6. The high voltage symbol flashes, the primary display
indicates >30 V, and the buzzer sounds if the voltage
(AC/DC) is <30 V.
