4.2.3 PROCEDURE

The Model 2234 Computer is manufactured with two versions of printed circuit
board (PCB) No.1. Each version has different designations and/or locations for the
test points and trimpot(s). Figure 4-1 shows the original version (DE-8992) and

POWER SUPPLY ADJUSTMENTS

A. The input power requirement decal is located on the top of the power supply
case, at the rear of the instrument. Verify that the proper potential is
applied.
B. Check all supply outputs for proper voltages. Only the +24 volts and +5
volts are adjustable. The power supply is a design which uses sense lines
for varying loads. Therefore, to insure optimum performance, the +24 V and
+5 V supplies must be adjusted accurately to ensure optimum performance.
