BATTERY INSTALLATION
WARNING: To avoid electric shock, disconnect the test leads from any
source of voltage before removing the battery door.
WARNING: To avoid electric shock, do not operate the meter until the
battery door is in place and fastened securely.
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
1. Disconnect the test leads from the meter.
2. Open the battery door by loosening the screw using a Phillips head
screwdriver.
3. Insert the battery into battery holder, observing the correct polarity.
4. Put the battery door back in place. Secure with the screw.
1. Press the DATA HOLD button to “freeze” the reading on the indicator. The
indicator “HOLD” will be appear in the display.
2. Press the DATA HOLD button to return to normal operation.
1. The BACK LIGHT button is used to turn the back light on or o ff . Press the
BACK LIGHT BUTTON to turn the back light on.
2. Press the BACK LIGHT BUTTON to turn the back light o ff .
1. ALWAYS turn the function switch to the OFF position when the meter is
not in use.
2. If “OL” appears in the display during a measurement, the value exceeds
the range you have selected. Change to a higher range.

Overvoltage Category II, Pollution Degree 2.
Category II includes local level, appliance, portable
equipment, etc., with transient overvoltages less
than Overvoltage Category III.
NOTE: If your meter does not work properly, check the fuses and batteries to
make sure that they are still good and that they are properly inserted.
OPERATING INSTRUCTIONS
DATA HOLD BUTTON
The Data Hold function allows the meter to "freeze" a measurement for later
reference.
BACK LIGHT BUTTON
NOTE: On some low AC and DC voltage ranges, with the test leads not
connected to a device, the display may show a random, changing reading.
This is normal and is caused by the high-input sensitivity. The reading will
stabilize and give a proper measurement when connected to a circuit.
