Preliminary Adjustment Procedure
Perform the following steps prior to adjusting the 3458A:
1 Select the adjustment area. You can adjust the 3458A on the bench or in a
system cabinet. The temperature of the adjustment environment should be
between 15
°C and 30 °C. The more thermally stable the environment is, the
more accurate the adjustment.
2 Connect the 3458A to line power and turn the multimeter on. Refer to
“Installing the Multimeter” in Chapter 1 of the 3458A User’s Guide for
information on setting the line voltage switches and installing the line power
fuse.
3 Remove all external input signals from the front and rear input terminals.
4 Select the DCV function (use the DCV key) and the 100 mV range (repeatedly
press the down arrow key until the range no longer- changes). (Refer to
Chapter 2 of the 3458A User’s Guide for more information on front panel
operation.)
5 Set the front panel Terminals switch to the Front position.
6 Allow the multimeter to warm up for 4 hours from the time power was applied.
(At this point. you can connect the 4-terminal short to the front terminals as
shown in Figure 3-1 on page 39 to prepare for the Front Terminal Offset
Adjustment.)
