Setup Time Attentions
Make sure that the RC return at input terminal has been in a stable state completely
(higher than 3 s) before accurate measurement.
Input >300 Vrms (or >5 Arms) will cause the self-heating of the signal conditioning
component to generate error which is included in the characteristics of the
instrument. Internal temperature variation due to the self-heating will cause an
additional error on the lower AC range. The error is smaller than 0.03% of readings
and will disappear after a few minutes.
NOTE
[1]: 20% over range on all ranges except DCV 1000 V, ACV 750 V, DCI 10 A, 3 A, and ACI 10 A, 3
A.
[2]: Specifications are for sine-wave inputs >5% of the range. For the 750 VAC range, it is
limited to 8 x 10
7
Volts-Hz. For 5 kHz to 8 kHz, add 0.13% of range additional error.
[3]: Specifications are for sine-wave inputs >5% of the range. For 100 μA, 1 mA, 10 mA, and
100 mA ranges, the internal current sensing resistor needs to be cooled if >1 A current is
applied for more than 15 minutes.
[4]: 10 A is only available for DM858. The max. current range for DM858E is 3 A. For continuous
current greater than DC 7 A or AC RMS 7 A, 30 seconds ON and 30 seconds OFF.
[5]: For frequency <100 Hz.
