Series 2600 System SourceMeter® Instruments Reference Manual Section 15: Performance Verification
Performing the verification test procedures
Test summary
• DC voltage output accuracy
• DC voltage measurement accuracy
• DC current output accuracy
• DC current measurement accuracy
If the Series 2600 is not within specifications and not under warranty, see the calibration
procedures in
Section 16 for information on calibrating the unit.
Test considerations
When performing the verification procedures:
• Be sure to restore factory front panel defaults as outlined above.
• Make sure that the test equipment is properly warmed up and connected to the Series 2600
output terminals (use 4-wire sensing for voltage).
• Make sure the Series 2600 is set to the correct source range.
• Be sure the Series 2600 output is turned on before making measurements.
• Be sure the test equipment is set up for the proper function and range.
• Allow the Series 2600 output signal to settle before making a measurement.
• Do not connect test equipment to the Series 2600 through a scanner, multiplexer, or other
switching equipment.
WARNING The maximum common-mode voltage (voltage between LO and
chassis ground) is 250VDC. Exceeding this value may cause a
break down in insulation, creating a shock hazard.
The Input/Output terminals of the SourceMeters are rated for
connection to circuits rated Installation Category I only, with
transients rated less than 1500V peak. Do not connect the Series
2600 terminals to CAT II, CAT III, or CAT IV circuits.
Connection of the SourceMeter terminals to circuits higher than
CAT I can cause damage to the equipment or expose the operator
to hazardous voltage.
Hazardous voltages may be present on the output and guard
terminals. To prevent electrical shock that could cause injury or
death, NEVER make or break connections to the Series 2600 while
the unit is on. Power off the equipment from the front panel or
disconnect the main power cord from the rear of the Series 2600
before handling cables connected to the outputs. Putting the
equipment into standby mode does not guarantee the outputs are
not powered if a hardware or software fault occurs.
Setting the source range and output value
Before testing each verification point, you must properly set the source range and output value as
outlined below:
