DMM6500 6½-Digit Multimeter with Scanning Calibration and Adjustment Manual Section 3: Adjustment
DMM6500-905-01 Rev. E June 2021 3-3
Adjustment overview
DMM6500 adjustment is performed using a remote connection through either an optional GPIB, LAN,
or USB interface. The calibration adjustment commands provided in this manual use the Test Script
Processor (TSP
®
) command language. There is no front-panel method for full adjustment.
You can use the Keithley Test Script Builder to send you adjustment commands. See "Test Script
Builder (TSB)" in the
Model DMM6500 Reference Manual
(DMM6500-901-01).
To use GPIB with your DMM6500, you must use the KTTI-GPIB Communication and Digital I/O
Accessory.
Recommended test equipment
The following table summarizes the recommended calibration equipment. Specified accuracy of all
functions and ranges is dependent on the precision of reference signals used during the adjustment
process. To achieve specified performance, adjustment reference uncertainties must be at least four
times smaller than the best corresponding DMM6500 one-year accuracy specification for measuring
that signal.
