Series 3700 System Switch/Multimeter Reference Manual
11-2
Document Number: 3700S-901-01 Rev. A / August 2007
Line power
The Series 3700 requires a line voltage of 100V-240V (±10%), and a line frequency of 50Hz or
60Hz.
NOTE
The line frequency is automatically sensed at power-up.
Calibration considerations
When performing the calibration procedures:
Make sure that the equipment is properly warmed up and connected to the appropriate
input jacks.
Make sure the calibrator is in OPERATE before you complete each calibration step.
Always let the source signal settle before calibrating each point.
If an error occurs during calibration, the Series 3700 will generate an appropriate error
message. See ―Error summary‖ for more information.
WARNING
Observe the following safety precautions when performing these tests:
Some of the procedures in this section may expose you to dangerous
voltages. Use standard safety precautions when such dangerous voltages
are encountered to avoid personal injury or death caused by electric
shock.
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 cable insulation voltage ratings must equal or exceed the maximum
voltage applied to the plug-in module terminals.
Calibration cycle
Perform comprehensive calibration at least once a year, or every 90 days to ensure the unit
meets the corresponding specifications.
