SpeciÀcation CM100 Flexible Current Meter Note 1: Measurement accuracy assumes a centrally positioned conductor, no external electrical or magnetic eld and within operating temperature range. See gure 2 and the position sensitivity error table below for additional errors where the conductor is not centrally positioned. Position from loop centre (refer to gure 2) A AC conversion: True rms. True rms AC current accuracy is specied from 2 % of range to 100 % of range. Crest factor: d 1.6 at full scale (30.00A/300.0A/3000A). d 3.2 at half scale (15.00A/150.0A/1500A). ELECTRICAL All specied accuracies are at 23°C ± 5°C, <80% RH for 1 year. Temperature Coefcient: 0.1 x (specied accuracy) per °C. (0°C to 18°C, 28°C to 40°C). ENVIRONMENTAL Operating environment: 0°C to 50°C, <80% RH, non-condensing Storage temperature: -10°C to 60°C, 70% RH Altitude: Up to 2000m GENERAL Display: Liquid crystal display with a maximum reading of 3150 digits. Overrange: “–OL–” is displayed Low battery indication: symbol is displayed when the battery voltage drops below the operational level Sampling rate: 2 times per second. Auto power off: After approx. 15 minutes Power: 2 x 1.5 V AAA batteries (IEC LR03, NEDA 24A) Battery life: 120 hours typical with alkaline Dimensions: Meter: 120mm (L) x 70mm (W) x 26mm (D) Probe cable length: 457mm (CM100/18), 1524mm (CM100/60) Probe cable diameter: 8.5mm nominal Cable length (probe to meter): 1.8m Weight: 286g approx. including batteries Includes: 2 x 1.5V AAA batteries and instructions
