Reverse voltage is indicated by "OL". Shorted elements will
indicate near 0V and an open element will indicate "OL" in both
polarities.
3.8 Frequency/duty cycle measurements (Electronic)
1. Set the function switch to the "Hz %"
position.
2. Press the Hz/% button to display "Hz".
3. Insert the black lead banana plug into the
negative COM terminal and the red test
lead banana plug into the positive +
terminal.
4. Apply the test probes to the points of the
circuit to be tested.
5. The frequency measured is displayed on
screen.
6. Press the Hz/% button again to display "%".
7. The duty cycle is displayed in percentage.
3.9 Autoranging/Manual range selection
When the multimeter is first turned on, it automatically goes into
Autoranging and automatically selects the best range for the
measurements being made. This is generally the best mode for most
measurements. When manual range selection is necessary, proceed
as follows:
1. Press the RANGE key. The "AUTO" display will turn off.
2. Press the RANGE key several times to scroll through the available
ranges until the range you want is displayed.
3. To exit Manual selection mode and return to Autoranging, press
and hold down the RANGE key for 2 seconds.
Manual ranging does not apply to frequency measurements.
3.10 MAX/MIN
When using the MAX/MIN function in Autoranging mode, the
multimeter will "lock" into the range that is used when MAX/MIN
is activated. If a MAX/MIN reading exceeds that range, an "OL"
will be displayed. Select the adequate range BEFORE entering
MAX/MIN mode.
1. Press the MAX/MIN key to activate the MAX/MIN measurement
mode. The "MAX" is displayed. The meter will display and hold the
maximum measurement until a new maximum value is measured.
