Section 13: Calibration Model 2601B-PULSE System SourceMeter Instrument Reference Manual
13-20 2601B-PULSE-901-01A April 2020
Environmental conditions
Temperature and relative humidity
Conduct the adjustment procedures at an ambient temperature of 18 °C to 28 °C, with relative
humidity of less than 70 percent (unless otherwise noted).
Product specifications that are listed as 18 °C to 28 °C assume adjustment has been done at 23 °C.
If the 2601B-PULSE is adjusted at a different temperature, the specifications apply to ±5 °C of that
temperature.
Line power
The 2601B-PULSE requires a line voltage of 100 V to 240 V at a line frequency of 50 Hz or 60 Hz.
The instrument must be adjusted within this range.
Warmup period
Allow the 2601B-PULSE to warm up for at least two hours before adjusting the instrument.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
above), allow additional time for the internal temperature of the instrument to stabilize. Typically, allow
one extra hour to stabilize an instrument that is 10 °C outside the specified temperature range.
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
2601B-PULSE terminals.
• Always allow the source signal to settle before adjusting each point.
• Do not connect test equipment to the 2601B-PULSE through a scanner or other switching
equipment.
• If an error occurs during adjustment, the 2601B-PULSE generates an appropriate error message.
See the Error summary list (on page 12-2) for more information.
