Introduction
Use the procedures in this section to calibrate the Model 2010. Calibration procedures
include:
• Comprehensive calibration: calibrate DC and AC voltages, DC and AC currents, and
resistance values.
• Manufacturing calibration: usually only performed at the factory
WARNING The information in this section is intended for qualified service personnel
only. Do not attempt these procedures unless you are qualified to do so.
All the procedures require accurate calibration equipment to supply precise DC and AC
voltages, DC and AC currents, and resistance values. Comprehensive AC and DC calibration can
be performed any time by an operator either from the front panel, or by using the SCPI
commands sent either over the IEEE-488 bus or the RS-232 port. DC-only and AC-only
calibration may be performed individually, if desired.
NOTE Manufacturing calibration is normally required in the field only if the Model 2010 has
been repaired.
Environmental conditions
Conduct the calibration procedures in a location that has:
• An ambient temperature of 18-28°C (65-82°F)
• A relative humidity of less than 80% unless otherwise noted
Warm-up period
Allow the Model 2010 Multimeter to warm up for at least two hours before performing
calibration.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
in the above section), allow extra time for the instrument’s internal temperature to stabilize.
Typically, allow one extra hour to stabilize a unit 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.
Line power
The Model 2010 Multimeter requires a line voltage of 100V/120V/220V/240V, ±10% and a
line frequency of 45Hz to 66Hz, or 360Hz to 440Hz.
