SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Model DMM7510 7-1/2 Digit Graphical Sampling Multimeter instrument. Specifications are the standards against which the DMM7510 is tested. Upon leaving the factory, the DMM7510 meets these specifications. Supplemental and typical values are nonwarranted, apply at 23 °C, and are provided solely as useful information.
Measurement accuracies are specified at the DMM7510 terminals under these conditions:
- Temperature 23 °C ±5 °C, 5% to 80% relative humidity, noncondensing
- After a 90-minute warmup period
- 1 PLC or 5 PLC measurement rate; 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)
Definitions:
- TACAL: Ambient temperature of last automatic calibration
- TCAL: Ambient temperature of last external calibration; factory calibration performed at 23 °C ±1 °C
- Power Line Cycle (PLC): 16.67 ms at 60 Hz and 20 ms at 50 Hz or 400 Hz line frequency; frequency automatically sensed at power up
