Get things done with this super slim jaw clamp on meter from Hioki.
| Measurement Principle | Instrument has two cores for voltage injection and current measurement. From the defined voltage and measured current, the total circuit loop resistance is calculated Note: For multi grounded systems only. In a multi-grounded system, the larger the number of grounding poles, the more accurate the measured value. |
| Earthing Resistance Range | 0.20 Ω (0.01 Ω resolution) to 1600 Ω (20 Ω resolution), 10 ranges, Zero suppression: Less than 0.02 Ω, Accuracy: ±1.5% rdg. ±0.02 Ω |
| AC Current Range | 20.00 mA (0.01 mA resolution) to 60.0 A (0.1 A resolution), 5 ranges, Zero suppression: Less than 0.05 mA, Accuracy: ±2.0% rdg. ±0.05 mA (30 Hz to 400 Hz, True RMS), Crest factor 5.0 or less (for the 60 A range, 1.7 or less) |
| Maximum Allowable Input | 100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50/60 Hz, requires derating at frequency) |
| Maximum Rated Voltage to Earth | 600 V AC CAT IV |
| Memory Function | 2000 data |
| Alarm Function | For resistance measurement and current measurement, Beeps when measured value is less than or greater than threshold |
| Display | Digital LCD, maximum 2000 dgt., Display refresh rate: 500 ms (2 times/s) |
| Waterproof and Dustproof | IP40 (EN60529) with clamp sensor closed |
| Power Supply | LR6 (AA) alkaline battery ×2, maximum rated power: 450 mVA, Continuous use : 35 hr (in-house testing conditions) |
| Core Jaw Diameter | Φ 1.26" (32 mm) |
| Dimensions | 2.87 x 8.58 x 1.69" (73 x 218 x 43 mm) |
| Weight | 21.9 oz (620 g) |
