Tempo CMB360B Testing and Troubleshooting PRO Milliamp Clamp Meter

The CMA-360B Pro is the true RMS milliamp clamp meter professionals rely on for accurate troubleshooting in complex electrical systems. Ideal for diagnosing issues in 2-wire irrigation systems, traditional irrigation wiring, pump motors, landscape lighting, and a wide range of electrical applications, this versatile tool is built to handle demanding environments.

Designed to detect leakage and pinpoint circuit faults with precision, the CMA-360B features an intuitive auto-range function that simplifies testing—just select the appropriate setting to measure AC or DC voltage, AC current, AC milliamp current (leakage), or resistance.

With true RMS capability, the CMA-360B delivers accurate readings even in noisy or unstable power conditions—critical for analyzing systems like pump motor current draw. It measures resistance up to 600k Ohms and offers microamp-level current resolution (1/1000th of a milliamp), allowing you to detect subtle issues that standard meters might overlook.

FEATURES

• True RMS response for AC voltage and current ranges for best accuracy with both smooth and noisy or distorted waveforms
• AC Current Measurement
  • 60A max range, ideal for all domestic and light industrial use
  • 6000 mA (6 A) range, ideal for lighter loads such as lighting
• AC Milliamp Current Measurement (leakage)
  • 6.000mA range has 0.001mA, 1μA resolution. 60.00 and 600.0mA ranges are also available. These are excellent for checking for leakage or diagnosing outdoor lighting and irrigation circuit troubles.
• Check for "Nuisance Tipping" (GFCI/RCD) or in irrigation systems to check digital decoders of landscape lighting or feedback signals in industrial control.
• Selectable Low Pass Filter to eliminate high-frequency components (>160 Hz) from measurements.
• 0.001 mA (1 μA) current resolution
• Auto Power Off
• Peak hold function can be left monitoring until trip occurs.
• Manual hold button allows the reading to be "held" perhaps where the display cannot be read due to orientation.
• Jaw opens to 23 mm, ideal for most domestic and light industrial cables.
• Zero button allows nulling out any "stray" field from nearby - our specially designed clamp does that better than most other clamp meters.
• Clamp Meter Supplementary Functions
  • Voltage AC and DC from 600.0 mV to 600.0V
  • Resistance to 600.0 to 600.00 k-ohms
  • Continuity test < 45 ohms
• Milliamp Meter Display backlight
• Overvoltage protected to CAT-IV 300V and CAT-III 600V.
• Supplied with a pair of test leads with removable arc-flash guards, an instruction manual, a carry case and 2 x AAA cells
