DMM 7510 7½-Digit Graphical Sampling Multimeter

Specification Conditions

This document contains specifications and supplemental information for the DMM7510 7½-Digit Graphical Sampling Multimeter instrument.

Specifications are the standards against which the DMM7510 is tested. Upon leaving the factory, the Model DMM7510 meets these

specifications. Supplemental and typical values are nonwarranted, apply at 23°C (73°F), and are provided solely as useful information.

Measurement accuracies are specified at the DMM7510 terminals under these conditions:

• Temperature 23° ±5°C, 5% to 80% relative humidity, noncondensing.

• After a 90-minute warmup period.

• 1 PLC or 5 PLC; for NPLC settings less than 1 PLC, add appropriate ppm of range for peak noise uncertainty from the RMS noise table.

• Autozero enabled unless otherwise noted.

• Remote sense operation or properly zeroed local operation.

• Calibration period: One year or two years (calibration period may vary depending on customer requirements).

• T

ACAL = Ambient temperature of last automatic calibration.

• T

CAL = Ambient temperature of last external calibration; factory calibration performed at 23° ±1°C.

RMS Noise (additional peak noise uncertainty) 7

Applies to ±ppm of range.

Peak noise uncertainty is included in DC specifications for

≥1 PLC.

Add peak noise uncertainty to measurements for <1 PLC.

Input impedance set to Auto.

NOTES

1. 20% overrange on all ranges except 1% for 1000 V range.

2. Relative to calibration accuracy.

3. Add per degree from T

CAL ±5°C.

4. When properly zeroed using the Rel function with external cables.

5. Specified within 30 days of autocalibration, T

OPER ±5°C from TACAL.

6. For signal levels greater than 500 V, add 0.02 ppm/V to the ppm of the readings specification for measurements exceeding 500 V.

7. Noise values are based on 1000 readings with autozero on and using low thermal 4-wire short. V

RMS noise is typical. Additional peak noise is guaranteed.
