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 2600B
output terminals (use 4-wire sensing for voltage).
•
Make sure the Series 2600B SMU is set to the correct source range.
•
Be sure the Series 2600B SMU output is turned on before making measurements.
•
Be sure the test equipment is set up for the proper function and range.
•
Allow the Series 2600B SMU output signal to settle before making a measurement.
•
Do not connect test equipment to the Series 2600B SMU through a scanner, multiplexer, or other
switching equipment.
The maximum common-mode voltage (voltage between LO and chassis ground) is 250 V DC.
Exceeding this value may cause a breakdown in insulation, creating a shock hazard that
could result in personal injury or death.
The input/output terminals of the Series 2600B System SourceMeter
rated for connection to circuits rated Measurement Category I only, with transients rated
less than 1500 V peak above the maximum rated input. Do not connect the Series 2600B
terminals to CAT II, CAT III, or CAT IV circuits. Connection of the Series 2600B 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 all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the Series
2600B while the instrument is powered on. Turn off the equipment from the front panel or
disconnect the main power cord from the rear of the Series 2600B before handling cables.
Putting the equipment into standby does not guarantee that the outputs are powered off if a
hardware or software fault occurs.
