From the “Local Calibration Menu” rotate the current encoder until the display shows
“CAL” “CL06”. Press the voltage encoder switch to view and change CL06 (upper volt
meter calibration point). When CL06
is viewed the top display will show “E.Hi mtr
CL06
”. The bottom display shows the calibration value.
9. When calibrating the upper volt meter calibration point (CL06) the power supply output
will be enabled at approximately 95% of the voltage rating. Verify the proper load
connections before proceeding. The upper voltage output (CL05) must be calibrated
prior to calibrating CL06.
10.
Press the “OPER” switch to enable the power supply output. The calibration value for
CL06 is updated automatically and displayed on the bottom display. After the
calibration value stabilizes press the voltage encoder switch to accept the new
calibration value and return to the “Local Calibration Menu” (the voltage encoder switch
must be pressed while in operate mode to accept the change to CL06). Optionally you
can press the OPER switch and return to standby mode (OPER/STBY lamp is off) to
cancel the change to CL06 and return the calibration value to its original value. Press
the voltage encoder switch to return to
the “Local Calibration Menu”.
11.
From the “Local Calibration Menu” rotate the current encoder until the display shows
“CAL” “CL07”. Press the voltage encoder switch to view and change CL07 (lower
voltage output calibration point). When CL07 is viewed the to
p display will show “E.Lo
Out CL07”. The bottom display shows the calibration value.
12. When calibrating the lower voltage output calibration point (CL07) the power supply
output will be enabled at approximately 10% of the voltage rating. Verify the proper
load connections before proceeding.
13.
Press the “OPER” switch to enable the power supply output.
14. Use the current encoder to adjust the output so that the volt meter across the output
terminals reads the proper value for 10% of the unit voltage rating. Calculate using -
unit voltage rating x 0.10
15. There are two ways to end the calibration of CL07. The first way is to press the OPER
switch and return to standby mode (OPER/STBY lamp is off) and then press the voltage
encoder to return to the “Local Calibration Menu”. If this method is used to end CL07
then proceed with step 16 below to calibrate CL08. Optionally it is possible to
automatically calibrate CL08 before ending CL07. To automatically calibrate CL08
press the voltage encoder switch while the unit is still in operate mode (OPER/STBY
lamp is on), the display will momentarily change to “…” while CL08 is calibrated and
then the unit will change to standby mode (OPER/STBY lamp is off) and will return to
the “Local Calibration Menu”.
16.
From the “Local Calibration Menu” rotate the current encoder until the display shows
“CAL” “CL08”. Press the voltage encoder switch to view and change CL08 (lower volt
meter calibration point). When CL08 is viewed the top display will show “E.Lo mtr
CL08”. The bottom display shows the calibration value.
17. When calibrating the lower volt meter calibration point (CL08) the power supply output
will be enabled at approximately 10% of the voltage rating. Verify the proper load
connections before proceeding. The lower voltage output (CL07) must be calibrated
prior to calibrating CL08.
