5-10. Frequency/Duty Cycle Measurements (Electronic)

1. Set the rotary function switch to the "Hz/%" position.
2. Press the Hz/% button to indicate "Hz" in the display.
3. Insert the black lead banana plug into the negative
COM jack and the red test lead banana plug into the
positive Hz jack.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
6. Press the Hz/% button again to indicate "%" on the
display.
7. Read the % of duty cycle on the display.

5-11. Autoranging/Manual Range Selection

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 key. The "AUTO" display indicator will turn off.
2. Press the RANGE key to step through the available ranges until you select
the range you want.
3. To exit the Manual Ranging mode and return to Autoranging, press and hold
the RANGE key for 2 seconds.
Note: Manual ranging does not apply for the Frequency functions.

5-12. MAX/MIN

Note: When using the MAX/MIN function in Autoranging mode, the meter will
"lock" into the range that is displayed on the LCD when MAX/MIN is activated. If a
MAX/Min reading exceeds that range, an "OL" will be displayed. Select the desired
range BEFORE entering MAX/MIN mode.
1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The
display icon "MAX" will appear. The meter will display and hold the maximum
reading and will update only when a new "max" occurs.
2. Press the MAX/MIN key again and the display icon "MIN" will appear. The
meter will display and hold the minimum reading and will update only when
a new "min" occurs.
3. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.
