Description

Description

The clamp meter MA445 supports True RMS technology to achieve accurate measurements on non-sinusoidal waveforms. The clamp meter supports AC/DC voltage, AC/DC current, resistance, capacitance, frequency functions, as well as Type K function when temperature measurements are required. The MA440 series of multimeters also includes the non-contact voltage detection (NCV) function.

Key Features

  • True RMS technology for accurate measurements regardless of waveform type
  • Jaw size 1.2" (30mm) for conductors up to 500MCM
  • Built-in non-contact voltage detection (NCV) function
  • Large backlit LCD screen and built-in flashlight
  • Includes functions: AC/DC voltage, AC/DC current, resistance, capacitance, frequency, temperature (with Type K sensor), diode test, continuity measurement
  • Relative measurement mode for voltage, resistance, and capacitance, data hold, auto power off, and low battery indicator

Package Includes

  • Test leads
  • Batteries (3x AAA)
  • Type K temperature sensor
  • Carrying case

Specifications

Dimensions

Maximum Jaw Opening
30.48 mm

Maximum Jaw Opening

The maximum cable or conductor diameter that the clamp can grip in order to perform a measurement.
with Test Leads
Yes

with Test Leads


It has measurement terminals that have a red wire for positive and a black wire for negative.
AC Current
400 A
Indication
Digital
Bluetooth
No
ISO/NIST Calibration Certificate
No

Features & Functions

Inrush Current
No

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
Yes
LoZ (Low Impedance / Low Impedance)
No

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)
No

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
Yes

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
Yes

Capacitor Capacitance Measurement

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