Remarks:
[1] Specications are for 0.5 Hour warm-up, “Slow” measurement rate and calibration temperature 18
℃
~ 28
℃
.
[2] 10% over range on all ranges except for DCV 1000 V, ACV 750 V, DCI 10 A and ACI 10 A.
[3] Specications are for 4-wire measure or 2-wire measure under “REF” operation. ±0.2 Ω of extra errors will be generated if perform 2-wire measure without “REF”
operation.
[4] Plus 0.02 mV of error per 1 V after the rst ±500 VDC.
[5] 30 seconds OFF after 30 seconds ON is recommend foe the continuous current that higher than DC 7 A or AC RMS 7 A.
[6] Accuracy specications are only for voltage measuring at input terminal. The typical value of current under measure is 1 mA. Voltage drop at diode junction may
vary with current supply. Adjustable voltage range : 0~ 4 V.
