Overview
Use the procedures in this section to calibrate the Keithley Instruments Series
3700 System Switch/Multimeter.
WARNING The information in this section is intended for qualified
service personnel only. Do not attempt these procedures
unless you are qualified to do so.
Some of these procedures may expose you to hazardous
voltages, that if contacted, could cause personal injury or
death. Use appropriate safety precautions when working
with hazardous voltages.
For the plug-in modules, the maximum common-mode
voltage (voltage between any plug-in module terminal and
chassis ground) is 300V DC or 300V RMS. Exceeding this
value may cause a breakdown in insulation, creating a
shock hazard.
All procedures in this section require accurate calibration equipment to supply
precise DC and AC voltages, DC and AC currents, and resistance values.
Calibration can be performed any time by an operator using the Instrument
Control Language (ICL) commands sent either over the IEEE-488 bus or
Ethernet. DC-only or AC-only calibration may be performed individually, if
desired.
