Calibration
Introduction
Use the procedures in this section to calibrate both the Model 6430 mainframe and the
Remote PreAmp. These procedures require accurate test equipment to measure precise DC
voltages and currents.
NOTE
Mainframe and Remote PreAmp calibration are performed separately. The main-
frame must be calibrated before the Remote PreAmp.
WARNING
This 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.
The Remote PreAmp connectors carry hazardous voltage. To prevent risk
of electric shock, connectors must be fully mated or safety covers must be
placed over the open connectors. Proper installation requires that the oper-
ator is protected from exposed voltages by insulation or barriers.
Environmental conditions
Temperature and relative humidity
Conduct the calibration procedures at an ambient temperature of 18-28
°
C (65-82
°
F) with
relative humidity of less than 60% unless otherwise noted.
Warm-up period
Allow the Model 6430 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 speci
fi
ed temperature
range.
Also, allow the test equipment to warm up for the minimum time speci
fi
ed by the
manufacturer.
Line power
The Model 6430 requires a line voltage of 100 to 240V at line frequency of 50 or 60Hz. The
instrument must be calibrated while operating from a line voltage within this range.
