Adjustment Considerations - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
Line power
The Series 2600B requires a line voltage of 100 V to 240 V at a line frequency of 50 Hz or 60 Hz. The
instrument must be calibrated within this range.
Warmup period
Allow the Series 2600B System SourceMeter
performing calibration.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
above), allow additional time for the instrument's internal temperature to stabilize. Typically, allow one
extra hour to stabilize an instrument that is 10 °C (18 °F) outside the specified temperature range.
Also, allow the test equipment to warm up for the minimum time specified by the manufacturer.

Adjustment considerations

When performing the adjustment procedures:
•
Make sure that the test equipment is properly warmed up and connected to the correct Series
2600B terminals.
•
Always allow the source signal to settle before calibrating each point.
•
Do not connect test equipment to the Series 2600B SMU through a scanner or other switching
equipment.
•
If an error occurs during calibration, the Series 2600B will generate an appropriate error
message. See
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.
Calibration adjustment cycle
Perform a calibration adjustment at least once a year to ensure the instrument meets or exceeds its
specifications.
