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 meter is not in use. This meter 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.

Range Button
When the meter is first turned on, it automatically goes into AutoRanging. 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 AutoRanging.(If backlight is turn on, please press BACKLIGHT button it will turn off).
4. To select Diode/continuity.

Data Hold Button
The Hold function allows the meter to “freeze” a measurement for later reference.

1. Press the HOLD button to “freeze” the reading on the indicator. The indicator “HOLD” will be appear in the display.
2. Press the HOLD button to return to normal operation.

Hz/duty
