Features & Functions

Inrush Current
-

Inrush Current

Ability to record the instantaneous inrush current (duration ~100ms) absorbed by electric motors, motor-driven devices, and compressors during their momentary startup.
True RMS
Yes

True RMS


The True-RMS method will provide the correct value of the alternating quantity regardless of its waveform.
NCV
No
LoZ (Low Impedance / Low Impedance)
-

LoZ (Low Impedance / Low Impedance)

Low impedance function that absorbs induced/parasitic voltages ("phantom" voltages or ghost voltages) from adjacent cables, ensuring that you measure only the actual line voltage.
VFD Mode / LPF (Low Pass Filter)
-

VFD Mode / LPF (Low Pass Filter)

Integrated low-pass filter that cuts off high-frequency harmonic noise (PWM) produced by variable speed drives, allowing accurate voltage and frequency measurement in Inverters.
Temperature Measurement
-

Temperature Measurement

Ability to measure temperature via a connected thermocouple (Type-K terminal), allowing temperature monitoring of pipes, refrigerants, and HVAC components.
Capacitor Capacitance Measurement
-

Capacitor Capacitance Measurement

Ability to test and measure capacitor capacitance, allowing the immediate diagnosis of worn starting capacitors in motors, pumps, and compressors.
