Verification
Use the procedures in this section to verify that the Keithley Instruments Series 3700A System
Switch/Multimeter's accuracy is within the
limits stated in the instrument’s one-year accuracy
specifications. Verifying the accuracy of your Series 3700A is recommended:
•
When you first receive the instrument to make sure that it was not damaged during shipment
•
To verify that the instrument meets factory specifications
•
To determine if adjustment is required
•
Following adjustment to make sure that adjustment was performed properly
The information in this section is intended for qualified service personnel only, as described
by the types of product users in the
. 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 300 VDC or 300 V
RMS
. Exceeding this value may
cause a breakdown in insulation, creating a shock hazard.
If the instrument is still under warranty and its performance is outside specified limits, contact your
Keithley Instruments representative or the factory to determine the correct course of action.
