Service Guide for DM3000 Series
[3] 20% over range on all ranges, except DCV 1000V, ACV 750V, DCI and ACI 10A range.
[4] Specifications are for sine wave input >5% of range. For inputs from 1% to 5% of range and
<50 kHz, add 0.1% of range additional error. For 50 kHz to 100 kHz, add 0.13% of range.
750 VAC range is limited to 8x10
7
Volt-Hz.
[5] Specifications are for sine wave input >5% of range. Add 0.1% of the range for the sine wave
input is 1%~5% of the range.
[6] Generally 30% of reading error existing at 100 kHz.
[7] As continuous current higher than 7A DC or AC RMS, 30 seconds needs to be off after connecting
30s.
Low Frequency Characteristics
Following three filter settings are available:
Slow: 3Hz~300 kHz
Mid: 20Hz~300 kHz
Fast: 200Hz~300 kHz
Measurement Considerations
Frequencies greater than upper settings are considered with no additional errors.
Settling Considerations
Applying >300VRMS (or >2ARMS) will cause self-heating in signal-conditioning components. These
errors are included in the instrument specifications. Internal temperature changes due to
self-heating may cause additional error on lower ac voltage ranges. The additional error will be less
than 0.02% of reading and will generally dissipate within a few minutes.
