Stellar Instruments CM355 TRMS Milli Amp AC/DC Clamp Meter

The Stellar CM355 is a True RMS AC/DC clamp meter for accurate measurement of low currents without disconnecting the circuit. With a high current resolution of 0.1 mA, it suits troubleshooting of low-current circuits, control systems, automotive electrical systems, industrial maintenance and electronic equipment. TRMS measurement gives reliable AC readings even on distorted or non-sinusoidal waveforms, and the compact jaw fits confined electrical panels and densely wired installations.

Features:

  • 0.1 mA resolution for AC and DC current
  • Measures both AC and DC current
  • DC current up to 10 A
  • AC current up to 20 A
  • True RMS (TRMS) measurement
  • AC/DC voltage measurement up to 300 V
  • Resistance measurement up to 500 kΩ
  • Continuity test with buzzer
  • Zero, Peak, Hold and LPF functions
  • Jaw opening up to 35 mm

1. What is the CM355 used for?

It measures low AC and DC currents without disconnecting the circuit. With 0.1 mA resolution, it suits troubleshooting of low-current circuits, control systems, automotive electrical systems, industrial maintenance and electronic equipment.

2. What current ranges can it measure?

  • DC current: 300.0 mA / 3.000 A / 10.00 A
  • AC current: 300.0 mA / 3.000 A / 20.00 A

Resolution is 0.1 mA, 1 mA and 0.01 A across the three ranges. (The datasheet prints the middle range as "3.000 mA", which is most likely a typo for 3.000 A.)

3. How accurate is it?

  • DC current: ±1% rdg + 10 digits
  • AC current: ±1% rdg + 5 digits
  • DC voltage: ±1% rdg + 2 digits
  • AC voltage: ±1.2% rdg + 5 digits

AC readings use True RMS, so they stay reliable even with distorted or non-sinusoidal waveforms.

4. Can it measure voltage and resistance as well as current? Yes. It measures AC/DC voltage up to 300 V on 50 V and 300 V ranges. It also measures resistance up to 500 kΩ across four ranges and has a continuity test with a buzzer that sounds below 15 Ω. Use the test leads supplied for these functions.

5. What is the largest conductor it can clamp? The specification table gives a maximum jaw opening of 35 mm, although the description text mentions a 23 mm jaw. Confirm the exact figure with the supplier if cable size is critical. Either way, it suits cables in confined panels and densely wired installations, but not large cables or busbars.

6. What are the power and physical specifications?

  • Battery: 3 × 1.5 V AAA
  • Display: 4-digit LCD, maximum reading 6000
  • Sampling rate: 2 readings per second
  • Dimensions: 206 × 76 × 33.5 mm
  • Weight: 270 g
