4. Operating instructions
Warning!
Risk of electrocution. High-voltage circuits, both AC and DC are very dangerous and should be measured with great care.
- Always push the power pushbutton 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.
- If "OL" appears in the display during a measurement, that value you are measuring exceeds the range you have selected. Change to higher range.
4.1. Preliminary Note
- Check the 9 V battery by setting the ON/OFF switch to ON. If the battery is weak, a "LO BAT" or "BAT" sign will appear on the left of display. If this does not appear on the display proceed as below. See "Maintenance" if the battery has to be replaced.
- The warning sign next to the test leads jack is for warning, that the input voltage or current should not exceed the indicated values. This is to prevent damage to the internal circuitry.
- The function switch should be set to the range, which you want to test before operation.
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.
4.2. Autoranging / manual range selection
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 the range be manually held, perform the following:
- Press the "RANGE" button. The "AUTO" indicator will extinguish and the currently selected range will be held.
- Press the "RANGE" button to step through the available ranges until you select the range you want.
- Press and hold the "RANGE" button for 2 seconds to exit the manual ranging mode and return to "AUTO" mode.
4.3. Backlight
The backlight function is used to illuminate the display when the meter is used at night or in dimly lighted area.
