CLAMP ON AC/DC HiTESTER 3288 [1000 A rms max. MEAN Value ] 3287 [100 A max.True RMS ] Field Measuring Instrument Compact & Easy With Guaranteed Accuracy! AC/DC Multi-Function Clamp 3288 AC/DC 1000A max. Actual-size 3287 AC/DC 100A max One-touch maintenance on all types of AC/DC equipment Dual Action Jaw ❑ Features ● The 3288, for high current measurements such as UPS emergency batteries and train motors: 10 m ) 9" .3 (0 m Handles measurements up to a maximum of AC/DC 1000 A, using an average value type measurement formula for AC mode to realize cost savings. (1.37") ø35 mm max. ● The 3287, which can handle even cogenerator / inverter energy-saving equipment: The 3287 performs accurate measurements of even small currents in the AC/DC 10.00 A range. In AC mode it also guarantees accuracy of true RMS measurements for frequencies from 10 Hz to 1 kHz. Handles low frequency to distorted currents including higher harmonics, simplifying maintenance of energy-saving equipment up to a maximum of 100 A. ● Multi-function clamp that simplifies equipment diagnosis: Besides AC/DC current measurement, it also contains DMM functions for voltage, resistance, and continuity checking. ● A slim core of only 10 mm (0.39"), so clamping is easy even in crowded wiring ● Independent-opening double-lever design ● No metal (iron core) exposure, ensuring enhanced safety ● CAT III 600 V (current) for emphasis on safety ● Test Lead Holder for convenient voltage, resistance, and continuity checking. ■ 3287/3288 Specifications (accuracy at 23˚C±5˚C (73˚F±9˚F), 80% rh) Function DC current*1 AC current*1 Range (Accuracy) 100.0 / 1000 A 3288 (±1.5%rdg.±5dgt.) 3287 (±1.5%rdg.±5dgt.) 10.00 / 100.0 A 100.0 / 1000 A (45 to 66 Hz; ±1.5%rdg.±5dgt.) 3288 (10 to 45 Hz or 66Hz to 500Hz; ±2.0%rdg.±5dgt.) 10.00 / 100.0 A (45 to 66 Hz; ±1.5%rdg.±5dgt.)
