3.5 ENGAGING THE LOAD
1. After selecting the mode and setpoint (PAR 3.4), momentarily press the LOAD pushbutton to
engage the UUT, causing the load to draw current from the UUT at the level determined by
the setpoint. LOAD pushbutton illumination changes to amber and the front panel displays
show the measured parameters: voltage, current and power.
2. Rotating CONTROL with the load engaged (LOAD indicator amber) causes the controlled
parameter to increase (clockwise) or decrease (counterclockwise) in steps at the resolution
selected in PAR 3.4, step 2 above. The VOLTS, AMPS and KW displays show the measured
parameters any time the load is engaged (LOAD indicator amber).
3.6 DISENGAGING THE LOAD
With the load engaged (LOAD indicator amber), disengage the load from the UUT by momen-
tarily depressing the LOAD pushbutton (illumination changes to steady green) causing the load
to stop drawing current from the UUT.
3.7 VIEWING CONFIGURATION INFORMATION
When the Mode is OFF (none of the mode LEDs are illuminated), momentarily depressing the
LOAD pushbutton (illumination changes to blinking green) allows configuration information to be
viewed. Rotating CONTROL clockwise sequences the VOLTS, AMPS and KW displays as fol-
lows (counterclockwise sequences in reverse order starting with Firmware Version).:

• IP Address (1st octet = left 3 digits of AMPS, 2nd octet = right digit of AMPS, left 2 digits
of VOLTS, 3rd octet = right 2 digits of VOLTS, left digit of KW, 4th octet = right 3 digits of
KW display.) To change the static IP address from the front panel, see PAR. 3.9. IP
