ⅠIntroduction
ETCR001F Flexible coil current sensor (Integrator), Rockwell coil Current
Sensor, using advanced Roche technology, is a non-ferromagnetic material in
the uniform winding of the coil, no hysteresis effect, almost zero phase error,
non-magnetic saturation phenomenon, high linearity. The flexible coil is the
derivative of the current to time. The integrator integrates the output voltage
signal (0 ~ 1V), realizes the measured current and outputs the complete signal
waveform. The measuring current range from 0.1A to tens of thousands
amperes. Mainly used for current, high harmonic current (up to 400 times),
complex waveform current, transient impact current, phase, power, power,
power factor detection. Equipped with integrator can be more easily
integrated into other test equipment, such as power quality analyzer, harmonic
analyzer, power parameter recorder, phase detection analyzer, industrial
control devices, oscilloscopes, high-precision digital multimeter, transient
Impact recorder, distributed measurement system, protection system.
ETCR001F Flexible coil current sensor (Integrator), Coil part without any
exposed metal conductor, non-contact measurement, safe and reliable; Its
small size, light weight, beautiful appearance, soft and flexible, suitable for
narrow environments and cable-intensive places; Wide measurement range,
high accuracy, high reliability, response frequency bandwidth (0.1Hz-1MHz),
the user can customize the length of the coil. Widely used in electricity,
communications, meteorology, railways, oil fields, construction, measurement,
scientific research and teaching units, industrial and mining enterprises and
other fields. Particularly suitable for relay protection, SCR rectifier, frequency
control, semiconductor switches, power electronic conversion equipment,

Warning! The battery cover is not covered
when the test is forbidden, otherwise there
is a danger.
Note the polarity of the battery, otherwise
damage the meter.
Can not mix old and new batteries
1. When the battery voltage is lower than 6.8V (± 0.2V),
the battery voltage indicator light is on, indicating that
the battery is low, replace the battery.
2. Make sure the device is in the off state, loosen the
battery cover screws, open the battery cover, replace
