or its voltage is lower than 30V, it will enter into the formal testing
process and inject the high-voltage on the primary display, the
insulation resistance in MΩ is indicated in-phase with analog bar; on
the secondary display, the tested insulation voltage in V (DC) is
indicated, the symbol " " flashes and the buzzer warns frequently
d) Hands free operation "TEST" button or pushing down the "TEST"
button in the "LOCK" status can exit from the "LOCK" status and
shutoff the high-voltage， synchronously, the resistance values is
indicated in the primary display will be held, and the secondary display
still be in the status of monitoring the insulation voltage for the tested.
e) Subsequently, discharge the balance insulation voltage of the tested
through the inner switch of the meter. Turning the function switch can
exit automatically from testing status during the process.
6. LOW RESISTANCE (CONTINUITY) MEASUREMENTS
a) Set the range switch to 400Ω/
b) Connect the red test lead to the VΩ terminal and black to the COM
terminal.
c) Connect the tips of the test leads to both ends of the circuit under test,
read resistance in Ω on the LCD. The two ranges (40.00/400.0Ω) can
be switched automatically; the primary display of the resistance in Ω,
flashes in synchronous with the analog bar.
d) When the impedance on circuit is below approximately ≤35Ω. It will
indicate by a continuous beeper.
e) The current isfrom200 to 220mA while the tested resistance is 0Ω
f) The high voltage symbol "
">30V" and the buzzer warns frequently if the voltage (AC/DC) is more
than 30V.
7. AC/DC VOLTAGE MEASUREMENTS
a) Set the range switch to ACV or DCV position
b) Connect red test lead to "VΩ" terminal and black test lead to terminal
"COM".
c) Connect test prods of test leads IN PARALLEL to the circuit being
measured.
d) Read the voltage value on LCD.
8. BATTERY SAVER (SLEEP MODE)
The meter will automatically enter the "sleep mode" if there is no function
change or button press for 10 minutes, but it works as soon as you turn
the rotary function switch or push down any button.
9. POWER TOOLS AND SMALL APPLIANCES
This test would also apply to other similar equipment that has a line cord.
For double insulated power tools, the megohmmeter lead shown
Position
" flashes along with a primary display of
