2. If "OL" appears in the display during a measurement, that value
you are measuring exceeds the range you have selected.
Change to 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.
3. Press the "POWER" pushbutton to turn the meter on and off.
4.1. 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:
1. Press the "RANGE" button. The "AUTO" indicator will
extinguish and the currently selected range will be held.
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" mode.
4.2. Backlight
The backlight function is used to illuminate the display when the
meter is used at night or in dimly lighted area.
1. Press the "HOLD" button (P 3355) or the backlight button
(P 3360) for more than 2 seconds, the "HOLD" indicator will
appear and backlight will be activated.
