Martindale CM69 TRMS AC Earth Leakage Clampmeter
CM69 is a high performance TRMS AC Leakage clamp meter with outstanding low current capability. The pocket sized clamp also measures AC-DC voltage and resistance. The advanced jaw design minimises the influence of conductor position and shields against external fields from other conductors to give more accurate and consistent results.
Earth leakage clamps operate by clamping around both the live and neutral conductors. They also measure the difference between the currents flowing, allowing the "leakage value" to be displayed. Alternatively clamping around the earth conductor displays the earth leakage current.
Features and Benefits
Peak hold
Switchable low pass filter
TRMS measurement
Troubleshooting of RCD nuisance tripping
Periodic measurement of leakage current @ 50 Hz to check for insulation deterioration
Accurate measurement of triple neutral currents and other distorted waveforms
Differential current measurement for appliance testing
Auto ranging
High contrast backlit display
Supplied with
TL16 test leads, soft carry case, alkaline batteries and manual
Martindale Trms AC Earth Leakage Clamp Meter
The Martindale AC earth leakage clamp meter is a new age device measures the current up to 60A AC/DC and voltage up to 600VAC/DC. The advanced jaw design minimises the influence of conductor position and shields against external fields from other conductors to give more accurate and consistent results. They also measure the difference between the currents flowing by displaying the ’leakage value’. Alternatively, clamping around the earth conductor displays the earth leakage current.
It includes TL16 test leads, a soft carry case, 2 x 1.5V alkaline batteries, and a user’s manual.
