3. Choose which of the calibration tests summarized in Table 2-2 you want to run at the
CAL: RUN prompt. Use the up and down range keys to scroll through the options;
select your choice by pressing ENTER.
Front panel short and open calibration
At the Model 2700 prompt for a front panel short, do the following:
1. Connect the Model 8610 low-thermal short to the instrument front panel INPUT and
SENSE terminals as shown in Figure 2-1. Make sure the INPUTS button is not pressed
in so that the front inputs are selected. Wait at least three minutes before proceeding to
allow for thermal equilibrium.
NOTE Be sure to connect the low-thermal short properly to the HI, LO, and SENSE termi-
nals. Keep drafts away from low-thermal connections to avoid thermal drift, which
could affect calibration accuracy.
