Use the procedures in this section to calibrate the Keithley Instruments Series 3700 System
Switch/Multimeter.
WARNING
The information in this section is intended only for qualified service
personnel. Do not attempt these procedures unless you are qualified to do
so.
All procedures in this section require accurate calibration equipment to supply precise DC and
AC voltages, DC and AC currents, and resistance values. Comprehensive calibration can be
performed any time by an operator by using the Instrument Command Language (ICL)
commands sent either over the IEEE-488 bus or Ethernet. DC-only or AC-only calibration may
be performed individually, if desired.

Remote comprehensive calibration procedure .................................................. 11-4
Environmental conditions
Conduct the calibration procedures in a location that has:
An ambient temperature of 18°C to 28°C (65°F to 82°F).
A relative humidity of less than 80%. unless otherwise noted.
Warmup period
Allow the System Switch/Multimeter to warm up for at least two hours before performing
calibration.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
above) allow extra time for the instrument‘s internal temperature to stabilize. Typically, allow one
extra hour to stabilize a unit that is 10°C (18°F) outside the specified temperature range.
Also, allow the test equipment to warm up for the minimum time specified by the manufacturer.
