OPERATION
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous
and should be measured with great care.
1.
ALWAYS turn the function switch to the OFF position when the Multimeter is not in use.
This Multimeter has Auto OFF that automatically shuts the meter OFF if 15 minutes elapse
between uses.
2. If “OL” appears in the display during a measurement, the value exceeds the range you
have selected. Change to a higher range.
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.
Mode Button
To select Diode/Continuity or DC/AC current
Range Button
When the meter is first turned on, it automatically goes into Auto Ranging. This automatically
selects the best range for the measurements being made and is generally the best mode for
most measurements. For measurement situations requiring that a range be manually selected,
perform the following:
1.
Press the RANGE button. The “AUTO” display indicator will turn off.
2. Press the RANGE button to step through the available ranges until you select the range
you want.
3. Press and hold the RANGE button for 2 seconds to exit the Manual Ranging mode and return
to Auto Ranging. (If backlight is turned on, press BACKLIGHT button to turn off).
Data Hold Button
The Data Hold function allows the Multimeter to “freeze” a measurement for later reference.
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.
