Calibration
Introduction
Use the procedures in this section to calibrate the Model 2430. These procedures require accurate
test equipment to measure precise DC voltages and currents. Calibration can be performed either
from the front panel or by sending SCPI calibration commands over the IEEE-488 bus or RS-232
port with the aid of a computer.
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.
Some of these procedures may expose you to hazardous voltages.
Environmental conditions
Temperature and relative humidity
Conduct the calibration procedures at an ambient temperature of 18 to 28°C (65 to 82°F) with
relative humidity of less than 70% unless otherwise noted.
Warm-up period
Allow the Model 2430 to warm up for at least one hour before 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 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
Model 2430 requires a line voltage of 100 to 240V at line frequency of 50 or 60Hz. The in-
strument must be calibrated while operating from a line voltage within this range.
Calibration considerations
When performing the calibration procedures:
•
Ensure that the test equipment is properly warmed up and connected to the Model 2430
front panel INPUT/OUTPUT jacks. Also be certain that the front panel jacks are
selected with the TERMINALS switch.
•
Always allow the source signal to settle before calibrating each point.
•
Do not connect test equipment to the Model 2430 through a scanner or other switching
equipment.
