4000 COUNTS AUTO RANGE
INTELLIGENT DIGITAL AC/DC CLAMP MULTIMETER
OPERATION MANUAL
This LCD Auto Range Intelligent Digital AC/DC clamp multimeter is a portable,
4000 counts multimeter. It is ideally suited for field, laboratory, shop and home
applications.
The meter can be connected with mobile phone by Bluetooth,
and display on phone by APP, you can remote monitoring the measurement
condition, the distance control is 10～15m.
1. SAFETY INFORMATION
The following safety information must be observed to insure maximum
personal safety during the operation at this meter.
1) When measuring voltage ensure that instrument is not switched to the
current range, resistance range, diode and continuity range, capacitance range
or temperature range.
2) Use extreme care when measuring voltage above 50V. especially from
sources where high energy is existed.
3) Avoid making connections to "live" circuits whenever possible.
4) Before making resistance measurements, diode or continuity test,
capacitance test or temperature test, ensure that the circuit under test is
de-energized.
5) Always ensure that the correct function and range is selected.
6) Extreme care should be taken when using the instrument to conjunction with
a current transformer connected to the terminals if an open circuit occurs.
7) Ensure that the test leads and probes are in good condition with no damage
to the insulation.
8) Take care not to exceed the over-load limits as given in the specifications.
9) Before opening the cover of the battery cabinet to replace batteries.
disconnect the test leads from any external circuit, set the selector switch to
"OFF" position.
10) Keep the fingers after the protection ring when measuring through the
instrument lead.
11) Change the battery when the symbol “
” appears to avoid incorrect data.
2. Panel Layout
1) Rotary Switch: Use this switch to select functions and ranges.
2) D.HOLD/ Back Light key: In any range, push the key, the present display
value will be locked and the " H " symbol will appear, push it again to exit.
Press “D.HOLD” button more than 2 seconds, the back light will light, press it
more than 2 seconds again, the back light will light off.
3) SELECT key: This key work on the "
" range. Push the key to
choose resistance, capacitance, diode or continuity test. Press “SELECT” in
“V
” range, choose AC voltage or DC voltage test.
4) RANGE Key: Press the “RANGE” key, the meter enters manual range mode,
press it more than 2 seconds again, return to auto mode.
5) Hz/Duty Key: On “ACV/ACA” or “Hz” range, press the “Hz/Duty” key, you
can choose the Frequency or Duty Cycle measurement.
6) REL Key: Press the “REL” key, the meter enters relative measuring mode,
“REL” is displayed on the LCD and the present reading becomes the reference
value and displayed on the display. Relative measurement
REL△=measurement value-Reference value. Press it again to exit.
7) LCD display: 4000 counts digit, full function symbol display.
8) T+VΩ Input Jack、COM Input Jack、T- Input Jack
