1) In the resistance mode, press
“FUNC/ZERO"
button,
it will switch among resistance, diode and continuity
detection by recycling.
2) In the voltage mode, press
"FUNC/ZERO"
button to
switch between AC and DC.
3) In the temperature mode, press
"FUNC/ZERO"
button
to switch between celsius(°C) and fahrenheit (°F)
degree.
4.4 Function Selection Function
4.6 Automatic Power-Off
1) If there is no operation during any 30 minutes after
turning the machine on, the meter will enter
suspended state, automatically powering off to save
the battery. Within 1 minute before shutdown, buzzer
will sound five times. The meter will then enter a
dormant state.
2) After automatic power-off, press
“FUNC/ZERO”
key,
the meter will turn on again.
3) If the user holds
“FUNC/ZERO”
key when powering
on, it will cancel automatic power-off function.
4.7 Measurement Preparation
1) Turn the transfer switch to turn on the power. When
battery voltage is low (about<2.4V), LCD displays
“ ” symbol, Replace the battery.
2) “ ” symbol means that input voltage or current
should not be more than the specified value, which
is to protect the internal line from damage.
3) Place transfer switch to required measuring function
and range.
4) When connecting line, first connect the common
test line, then connect charged test line. When
removing line, remove charged test line first.
4.8 Current Measurement
Warning
Electric shock hazard. Remove the probe measuring with
current clamp.
1) Measuring switch is placed to position A. At this time,
the meter is in AC current measurement state.
Choose appropriate measuring range.
2) Hold the trigger, open clamp head, clip one lead of
measurement circuit to be tested in the clamp.
4) Read the current and frequency value on the LCD
display.
Note:
1) Clamping two or more leads of circuit to be tested
simultaneously will not get the correct measuring
results.
2) To get accurate reading, connect the lead to be
tested at the center of current clamp.
3) “ ” indicates that maximum input AC current is 150A.
Note:
1) When the meter is in the maximum/minimum value
measurement state, it is in manual measuring range
mode.
2) When the meter is in the temperature measurement
state, it can't switch to maximum/minimum value
measurement mode.
4.5 Current Clearing Function
In the current mode, press
“FUNC/ZERO”
key more
than 2 sec, the meter will clear the display of current
value.
