1. Summary
Uniks C6 digital AC clamp meter is a stable, safe and reliable
instrument. The circuit of the instrument takes integrated circuit as the core
and is equipped with a full range overload protection circuit. It has a novel
appearance and can be used to measure AC current, AC/DC voltage,
temperature, frequency, resistance, capacitance, diode and open-closed
circuit measurement. It is a superior instrument special for electricians.
1.1. Safety Standards
This instrument is designed and manufactured according to the safety
standards IEC61010-1 and IEC61010-2-032 for electronic measuring
instruments and hand-held current clamp meters, and meets the safety
standards of double insulation CAT Ⅲ 600V and pollution position 2.
1.2 Safety Signs
Warning sign, requiring operation with caution.
Can be used on dangerous live conductors.
Double insulation protection (Class II).
Conform to European Union (EU) standards.
Grounding.

Cautions
•Please read the instructions carefully before using the instrument,
and pay special attention to the contents of " ". Please follow the
operating instructions of "".
•Ensure that the instruments and probes coming with the package
meet the requirements of safety standards. If the probe is damaged,
replace it with a probe of the same model or electrical specification.
•Before use, check the instrument and probes. If the probe is exposed,
the housing is damaged, and the display is abnormal, do not measure.
•When measuring, do not tap the unused input terminal.
•When the measuring voltage is higher than 60V DC or 30V AC, be
careful and remember to keep your fingers behind the hand shelter
of the probe.
•When the range of to-be-measured value is uncertain, set the
function range to the maximum range position. Do not exceed the
input limits specified for each range.
•Do not measure a voltage higher than the allowable input value.
•Before switching the function range switch, the probe shall leave the
circuit under test.
•Before conducting in-circuit resistance measurement, cut off the
power supply and release all charges at both ends of all capacitors.
•Do not expose the instrument to strong light, high temperature or
humidity.
•Do not tap bare wires, connectors or circuits being measured with
bare hands.

4. Data-hold key/Backlight-display button
•Tap the "BL/HOLD" button, the final reading will be maintained on the
display and " " is displayed. Tap the "BL/HOLD" button again, and
the instrument will return to the normal measurement state.
•Press and hold the "BL/HOLD" button for about 2 seconds to turn on
or off the LCD backlight, and it will turn off automatically after about
30 seconds.
5. Inrush current test button
•Tap the "INRUSH" button to turn on or off the inrush current
measurement function
•Press and hold the "INRUSH" button for more than 2 seconds to turn
on or off the lights.

Maximum display value: 5999.
7. INPUT terminal
In addition to the AC current, the red probe contacts positive input
terminals.
8. COM terminal
In addition to the AC current, the black probe contacts negative input
terminals.
9. Manual range key/Low-pass filter button
•Tap the "LPF/RAN" button during the automatic range to switch to the
manual range.

•Press and hold this key for more than 2 seconds during the manual
range to switch back to the automatic range.
•During the AC current and AC voltage automatic measuring, press and
hold the "LPF/RAN" button for about 2 seconds to turn on or off the
LPF mode.
10. Maximum/Minimum value button
•When at the voltage, current, resistance and temperature positions,
tap the "MIN/MAX" button to switch between displaying the
maximum and minimum values.
•Press and hold the "MIN/MAX" button for more than 2 seconds to
exit the maximum and minimum value measurement.
11. Function selection button
•In " " position, it is used to switch between current value and
current frequency.
•In " " position, it is used to switch between the frequency of AC
voltage, DC voltage and AC voltage.
•In " " position, it is used for switching between resistance,
capacitance, diode measurement and open-closed measurement.
•In "Hz%" position, it is used to switch between frequency and duty
ratio.
•In"℃℉"position, It is used to switch between the temperature units
of ℃ and ℉.
•In " " position, it is used to switch between DC voltage and AC
voltage.

the light on or off.
•The light turns off automatically about 1 minute after it is turned on.
3. Instructions
WARNING
Do not measure any voltage higher than 600V DC or 600V
AC RMS to avoid electric shock and/or damage to the
instrument. Do not apply voltage exceeding 600V DC or 600V
AC RMS between the common terminal and the ground to
prevent electric shock and/or damage to the instrument.
3.1 AC and DC voltage measurement
Insert the red probe into the "INPUT" jack, and the black probe into
the "COM" jack. Switch the function range switch to " " position, tap
the "SEL" button to switch between AC voltage, DC voltage and frequency
measurement modes, and connect the probes to the measured signal.
3.2 AC voltage and frequency measurement
•When measuring AC voltage, tap the "SEL" button to switch the
display of the voltage value and frequency of the measured voltage;
