Red backlight as warning indication:
Incorrect wire connection will cause negative active power and cause the red backlight to flash.
The red backlight flashes when the measured voltage is >1000VAC and current >1000A.
The red backlight flashes if the phase sequence is inverse.
Analyzing fixed-frequency harmonic:
Long press RANGE button to power on the clamp to HARM position, then the clamp enters
the fixed-frequency harmonic setting interface, as shown below:
Press “MAX MIN” to select ones place, tens place, hundreds place and thousands place of
the value in auxiliary display. Press “ ” or “ ” to change partial values.
When “HOLD” is pressed after the setting is completed, the clamp enters fixed-frequency
harmonic analysis mode, “SET” in auxiliary display and fixed frequency are displayed
alternately for one second, as shown below, other displayed values are same with harmonic
sweeping analysis mode.
To reset fixed-frequency mode of other frequencies, please switch to other positions and
then return to HARM position.
XII. Technical Specifications
Accuracy: ± (a% of r b digits), one-year warranty period
Ambient temperature: 23°C±5°C (73.4°F±9°F); relative humidity:
≤
75%
Note:
The temperature condition of accuracy is 18°C~28°C, the fluctuation range of ambient
temperature keeps within ±1°C. If the temperature is 18°C or >28°C, the additional error of
temperature coefficient is “0.1 × (specified accuracy)/°C”.
To ensure measurement accuracy, please place the measured conductor at the center of the
clamp jaws. Error of ±1.0% of reading will be produced if the measured conductor is not
placed at the center of the clamp jaws.
