Amprobe 330-EUR Clamp Multimeter
Amprobe 330-EUR Clamp Multimeter is a handheld AC/DC clamp meter built for industrial motor maintenance, motor testing and HVAC diagnostics. It measures AC and DC current up to 1000 A and AC and DC voltage up to 1000 V. Its 51 mm jaw opening provides access around larger conductors, while True-RMS sensing supports accurate measurements on distorted waveforms.
For work with variable-frequency drives, a low-pass filter helps the meter measure current and voltage on non-sinusoidal signals. The Amp-Tip function provides precise low-current measurement down to a tenth of an amp. Amprobe 330-EUR Clamp Multimeter also supports inrush current testing, 3-phase and motor rotation indication, capacitance measurement and DC microamp testing.
Field-focused features include a backlit LCD, non-contact voltage detection and three input jacks for additional test functions. Temperature measurement is available through a Type-K input, making the meter suitable for HVAC diagnostic tasks as well as industrial electrical work. Amprobe 330-EUR Clamp Multimeter carries CAT IV 600 V and CAT III 1000 V safety classifications and operates from AA battery power.
