2-1. Power switch: turn on/off the power
2-2. Hold and backlight key: short press to the
measured value is held on LCD and "HOLD"
symbol displays. Press it again "HOLD" symbol
disappears and meter is exited the holding
mode. Long press to turn on/off the backlight.

Usage
Check the 9 V battery and press the "POWER"
•
button. If the battery is depleted, the battery
symbol appears on the screen.
The signs near the connectors warn about not
•
exceeding the inward voltage or current. This is
to prevent damage to the inside circuits.
Before measuring set the function switch to the
•
desired position.
If you are unsure about the magnitude of the
•
result, set the switch to the highest possible
range and go backwards until you reach the
correct setting.
DC and AC voltage measuring
Connect the black measuring wire to the „COM",
•
and the red one to the „V / Ω" connector.
Set the function switch to the correct "V"
•
position and connect the wires to the voltage
source paralelly.
Note:
If you are unsure about the magnitude of the result, set the switch
•
to the highest possible range and go backwards until you reach
the correct setting.
Set the DC / AC switch to the desired (DC or AC) function.
•
If only an „OL" is displayed on the screen, it signals overload.
•
Switch to a higher range.
Do not connect voltage exceeding DC 1000 V / AC 700 V to the
•
connectors. Results may be displayed at higher voltages also, but
this may lead to damage to the inside circuits.
Do not touch the high voltage circuits while measuring.
