DMM7510
7½-Digit Graphical Sampling Multimeter
Specification Conditions
This document contains specifications and supplemental infor-
mation for the Model DMM7510 7½-Digit Graphical Sampling
Multimeter instrument. Specifications are the standards against
which the Model 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 accura-
cies are specified at the Model DMM7510 terminals under these
conditions:
• Temperature 23° ±5°C, 5% to 80% relative humidity, non-
condensing.
• After a 90-minute warmup period.
• 1 PLC or 5 PLC; for NPLC settings less than 1 PLC, add appro-
priate 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.
Examples:
• 10V at 0.006 PLC: 1.2 (from Accuracy table) + 11 (additional peak noise uncertainty) = 12.2 ppm of range.
• 10V at 1 PLC: 1.2 + 0 = 1.2 ppm of range.
