Introduction
Use the procedures in this section to verify that the Keithley Instruments Series
3700 System Switch/Multimeter's accuracy is within the limits stated in the
instrument‟s one-year accuracy specifications. Verifying the accuracy of your
Series 3700 is recommended:
When you first receive the instrument to make sure that it was not damaged
during shipment
To verify that the unit meets factory specifications
To determine if calibration is required
Following calibration to make sure that calibration was performed properly
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.
