Adjustment Sequence

Calibration adjustment is a menu-driven process. Fluke Calibration recommends that
calibration be done in the order specified by the menu. However, each step is independent
and can be performed separately if necessary, with the exception of the TC function. The
TC calibration adjustment must be done in the order shown in the menu (steps 1-18). TC
read uses the internal source mode and it must be adjusted after TC source. Do not source
with an external instrument for TC read. Connect a DMM and adjust the output to the
necessary value with the PC keyboard.
Exit the calibration mode at any time by typing 18.

Steps 1 through 4: DC mV and DC V Source Adjustment

Voltage output adjustment is done for four distinct ranges. Each range can be adjusted
separately with menu selections 1 through 4. The adjustment of each range uses the same
procedure and is done in two parts. The first part sets the zero and span values. The
second part fine-adjusts the zero, span, and adjusts the linearity if necessary. See Table 3
for the test equipment used for this procedure.
Connect the Product volts HI and LO to the DMM input. Set the DMM to measure
dc volts. See Figure 12 for connections.
