Low
ll"1o Unipolar Mode Calibration
1. Connect the DVM between the A1 and A2 output
terminals of the 59501A. Connect the DVM com¬
mon to the AT terminal.
2. Set the mode switch on the rear of the 59501A to
UNIPOLAR.
3. Apply power to the HP 85 and the 59501A. Allow
a 30 minute warm-up.
Figure 38 is a program for calibrating the 59.501A for
use as a low level unipolar DC signal source. It includes
set-up and calibration routines.
Instructions:
Enter the program and press . © , All calibration
operations are displayed on the CRT of the HP 85. To
run the program again, press then
