1) Turn the function switch to the voltage( V, mV) or the current(µA,
mA, A )position.
2) Press the SELECT key to select the range of frequency. (The display shows
the unit of frequency.)
3) Plug the black testing lead into the “ COM ” input terminal.
Plug the red testing lead into the “ • V • Ω • • TEMP ” input
terminal when voltage measurement.
Plug the red testing lead into the suitable input terminal (“ A” or “µA•mA”)
for current value when current measurement.
4) Contact the measuring probe to the under test and then read the value
when it stabilizes. The display shows frequency value in main-display
and duty cycle ratio value in sub-display.
● AUTO HOLD Function
The instrument can automatically retain the measured value
when the testing leads are handled as described below.
1) Press the HOLD key to select u ûêAuto hold function.
(The display shows the“ A•H ” symbol.)
2) Connect the testing leads to the circuit under test.
3) When the reading stabilized, the buzzer sounds.
4) Remove the testing leads from the circuit under test.
5) The display shows the measured value that is retained.
You can repeat steps 2) to 4)as many times as you like as long as the
display shows the “ A•H ” symbol.
Note
• In DC/AC voltage measurement, the Auto hold function is only available
for ranges greater than the 5V range.
• This function is not available for Temperature, Capacitor and Frequency
measurement.
• The Auto hold function can not be applied to unstable signals.
