600V/0A ~ 25A will map to 4-20mA as shown in Figure 3-7 (c).
d. Selecting Vref=5KOhm means the DC Power Supply’s output 0V -
600V/0A ~ 25A will map to 0-5KOhm as shown in Figure 3-7 (d).

APG VMEAS/APG IMEAS has 4 selections: NONE / Vref(0-5V) /
Vref(0-10V) / Iref(4-20mA) where:
a. Selecting Vref=5V means the DC Power Supply’s measurement
output 0 - 600V/0A ~ 25A will map to 0-5V as shown in Figure 3-8
(a).
b. Selecting Vref=10V means the DC Power Supply’s measurement
output 0 - 600V/0A ~ 25A will map to 0-10V as shown in Figure 3-8
(b).
c. Selecting Iref=4-20mA means the DC Power Supply’s measurement
output 0 - 600V/0A ~ 25A will map to 4mA-20mA as shown in
Figure
