Note :
1. BLUE KEY switch and RANGE Switch resets all special
modes other than HZ mode .
2. HZ switch is only used to toggle between frequency
measurement mode and voltage or current measurement
mode, and thus can not be nested in any other special
modes.
3. The bar graph always shows the current value, regardless
of special mode.
7. Light switch — Press the switch to turn on or turn o the
back-light.
8. HZ — If “ HZ” switch is pushed in voltage or current
measurement mode, the meter enters frequency
counter mode with automatic range selection.
Therefore, pressing “RANGE” switch in HZ
mode does not change the frequency range.
However,“RANGE” switch changes the sensitivity
of frequency detection. If the input signal has a
small amplitude, the user shall increase the
sensitivity.
Note : Since HZ mode is treated as a temporary frequency
measurement in voltage or current mode, pressing
“RANGE” switch in HZ mode also changes the full
scale range of the original voltage or current mode
after VAHZ mode is cancelled.
9. PEAK H — The precision of PEAK hold mode
measurement can be enhanced by calibration. Calibration
for PEAK hold mode is invoked by pressing “PEAK H ”
switch for more than 2 seconds until the “caL” is displayed.
Pressing the “Peak H ” switch to toggle between PMAX
and PMIN.Pressing “Peak H ” switch and held for longer
than one second to release the peak hold mode.
10. Range Switch, (Manual Range) — “Range” switch is
pressed to select manual ranging and to change ranges.
When “Range” switch is pressed on “RANGE” annunciator
on the LCD appears.
Press “RANGE” switch to select appropriate range to be
used.
Press “RANGE” switch and hold for 2 seconds to return
to Autoranging. In “ HZ” mode “RANGE” is not used
to change the full scale frequency range, but change the
sensitivity of frequency measurement.
11. Blue Switch — Press the switch to measure AC Voltage
/ Current or DC Voltage / Current in the voltage / Current
mode, or to measure Resistance or continuity or diode in
Ω / / mode or to measure Frequency or RPM in RPM
in Hz / PRM mode.
