AC SPECIFICATIONS
[1] Input impedance: 10 MW (nominal).
[2] Current can be measured up to 440 mA continuously. An additional 0.2% needs to be added to the specifi ed accuracy if the signal measured is in the range of
[3] Current can be measured up to 10 A continuously with a maximum operating temperature of 50 °C. An additional 0.3% needs to be added to the specifi ed accuracy
[4] The maximum open voltage is < 2.8 V. For instant continuity, the built-in buzzer sounds when resistance is < 10.0 W.
[5] The accuracy of 1 kW and 10 kW is specifi ed after Null function, which is used to substrate the test lead resistance and the thermal effect.
[6] For the range of 100 MW, the R.H. is specifi ed for < 60%. The temperature coeffi cient will be 0.15 times of specifi ed accuracy as > 50 MW.
[7] Overload protection: 1000 V RMS for circuits < 0.3 A short circuit current. The built-in buzzer sounds when reading is approximately below 50 mV and audible single
[8] Input impedance: 10 MW (nominal) in parallel with <100 pF, with overload protection of 1000 V RMS
[9] Crest factor ≤ 3. For non-sinusoidal waveforms with crest factor up to 3, add 2% reading + 2% full scale typical.
[10] Current can be measured from 50 mA to 440 mA continuously. An additional 0.2% needs to be added to the specifi ed accuracy if the signal measured is in the range of
[11] Current can be measured from 0.5 A up to 10 A continuously with a maximum operating temperature of 50 °C. An additional 0.3% needs to be added to the
[12] AC voltage and AC current specifi cations are AC coupled. True R.M.S. Measurement is valid from 5 % of range to 100 % of range.
