Amprobe 37XR-A TRMS Digital Multimeter

Amprobe 37XR-A TRMS Digital Multimeter combines True-RMS measurement with a broad set of electrical, component and logic test functions. It measures AC and DC voltage and current, resistance, capacitance, inductance and frequency. Logic testing, diode testing, duty cycle measurement and a continuity beeper add further options for electronics fault finding at the bench or on the job site.

For clear readings, the meter uses a backlit 4-3/4 digit LCD with 10,000 counts and a 41-segment analogue bar graph. Autoranging helps simplify measurement setup, while min/max, average, relative, peak and data hold functions give users several ways to capture and review readings. The nominal display update rate is two readings per second.

Amprobe 37XR-A TRMS Digital Multimeter also includes practical features for regular testing work. An input warning tone alerts the user when the test leads are connected to the wrong jack, while the 10 A AC/DC input is fully safety fused. Auto power-off helps preserve the 9 V battery, and a separate battery and fuse door provides direct access for maintenance.

 

Key Benefits
  • True-RMS measurement supports AC voltage and current testing across the stated frequency ranges.
  • Component test functions cover resistance, capacitance and inductance for a wider range of electronics checks.
  • Logic testing to 20 MHz and frequency measurement to 40 MHz support electronic signal testing.
  • The backlit 10,000-count display improves reading visibility and includes a 41-segment analogue bar graph.
  • Min/max, average, relative, peak and data hold functions help capture and compare measurement results.
  • An input warning tone alerts the user if the test leads are connected to the wrong jack.
  • Autoranging reduces the need to select measurement ranges manually.
  • Auto power-off helps extend battery life when the meter is left unused.
  • A separate battery and fuse access door makes routine battery and fuse access easier.
  • The Magne-Grip™ Holster uses a magnetic hanging strap to support hands-free positioning.

 

Common Applications

Amprobe 37XR-A TRMS Digital Multimeter is suitable for a range of testing, maintenance and inspection tasks, including:

  • Electronics troubleshooting at the bench or on the job site
  • AC and DC voltage measurement
  • AC and DC current measurement
  • Resistance and continuity testing
  • Capacitance and inductance measurement
  • Frequency and duty cycle measurement
  • Logic testing
  • Diode testing
  • Min/max, average, relative and peak measurement checks
