Window Filter and Memory (buffer)

Window Filter Size

0 to 10% of reading, where 0 averages all readings.

Memory

Up to 27.5 million timestamped readings with the compact buffer style, with additional memory available

using an external USB flash drive.

Maximum Internal Memory (Buffer) 27.5 million readings with the compact buffer style (6½-digit without formatting), 11 million readings with

the standard or full buffer style.

General Instrument Specifications

Specification Conditions

This document contains specifications and supplemental information for the DMM7510 Precision Sampling

Digital Multimeter instrument. Specifications are the standards against which the DMM7510 is tested. Upon

leaving the factory, the DMM7510 meets these specifications. Supplemental, typical, and characteristic

values are non-warranted, apply at 23°C, and are provided solely as useful information. All specifications

apply to front or rear terminal inputs, except 10 A specifications (rear terminals only).

Input Protection

1010 V DC (715 V

on sense HI, sense LO terminals; 250 V rated current input terminal; fused 3 A and 10 A ranges; current

input terminals protected to 1 kV.

3 A Input Fuse Protection

3.5 A, 1 kV fast blow type; Keithley part number DMM7510-FUSE-3A.

10 A Input Fuse Protection

11 A, 1 kV fast blow type; Keithley part number DMM7510-FUSE-10A.

AC Voltage input

Maximum DCV: 1000V on any AC voltage range.

Common Mode Isolation

500 VDC or ACVpeak LO to chassis. All terminals >10 G

Ω, <350 pF any terminal to chassis.

Power Line

Universal input, 100 V to 240 V.

Line Frequency

50 Hz or 60 Hz, automatically sensed at power-up.

Power Consumption

60 VA.

Operating Environment

Specified for 0° to 50°C,

≤80% relative humidity at 35°C, altitude up to 2000 meters.

Storage Environment

–30° to 70°C.

Real Time Clock

Lithium battery backup (3+ years battery life).

EMC

Conforms to European Union EMC Directive.

Safety

NRTL listed to UL61010-1, and CSA C22.2 No 61010-1; conforms with European Union Low

Voltage Directive.

NOTES

99. For DC or AC coupled, the trigger level can be set up to 100% of measure range.

100. Rising or falling edge triggering supported. Window trigger requires setting two independent levels.

101. Trigger event occurs after the threshold crossing at a time determined by total trigger latencies.

102. Accuracy specifications require user

off. NPLC 0.0005 (DC voltage/DC current) or aperture 1 µs for digitize voltage or digitize current. Specified for fixed range, autozero off. For digitized DC voltage AC coupled, add 0.5%.

For DC current and digitized DC current 3 A or 10 A ranges, add an additional 2%.
