60.00 k 0.01 k - 0.8% + 3 0.8% + 3 0.8% + 3 95 A0.7 V
Notes for resistance specifications:
1 Overload protection: 600 Vrms for short circuits with <0.1 mA current
2 Maximum open voltage is <1.4 V
3 The accuracy is specified after the Null function is used to subtract the test lead resistance and thermal effect (by shorting
the test leads).
