Duty-cycle Measurement
1. Set the function/range switch to the FREQ position.
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack. NOTE: The multimeter will be in auto-ranging.
3. Press the Hz/% button twice, the % will appear on the LCD.
4. Touch the test lead tips across the circuit under test.
5. The duty-cycle and % will be shown on the LCD.
CAUTION: Never input the voltage over 250 V AC/DC.
Temperature Measurement (Use Temperature Probe; sold separately)
1. Set the function/range switch to the TEMP position. If you wish to measure
temperature in ˚C, set the function switch to the ˚C range. If you wish to measure
temperatures in ˚F, set the function switch to the ˚F range.
2. Insert the negative(-) test lead of the temperature probe into the "COM" jack
and the po) test lead into the mA/
µ
A TEMP jack.
3. Touch the temperature probe head to the part whose temperature you wish
to measure. Keep the probe touching the part under test until the reading
stabilizes (about 30 seconds).
4. Read the temperature on the LCD. The digital reading will indicate the proper
decimal point and value.
CAUTION: Do not measure temperatures of metal parts when any voltage is
present on them. Temperature measurements only use test leads with
temperature probes, otherwise the audible signal will sound.
Relative Value Measurement
During the measurement of the reference or base value, press the relative button.
The "
△
will show on the LCD and the value will be stored in memory as a reference
for future use. At the following measurement, the LCD will only show the different
value between the measured device and base unit. To cancel this function, press
the "REL" button until "
△
disappears from the LCD.
Maintenance
Always keep the multimeter dry.
Clean the multimeter with a damp cloth only.
Remove the batteries if the multimeter will not be used for a long period of time.
