NOTE: You can now use the keypad of the controlling power supply to set parameters for the
controlled power supply. However, the messages and values displayed in step 2 above
are not valid at this time. These messages/values are stored in the buffer of the con-
trolling power supply; they are updated with valid information from the controlled power
supply only by executing the commands indicated in steps 3 through 5 below.
3. Ensure that the controlled power supply output is disabled by pressing DC OFF. Message
M3 in the upper right corner of the display reads OD. (Remember, this command must be
executed even if the display already reads OD to begin with.)
4. If the controlled power supply is a Model MR or MGR unit, press SHIFT then DC OFF.
Read Message M2 on the display to establish the existing polarity of the controlled power
supply (P+, non-reversed or P
−, reversed). To toggle the polarity press SHIFT then DC
OFF. (Again, this command must be executed even if the original polarity displayed is the
desired polarity.)
5. Set the commanded mode of the controlled power supply by pressing SHIFT and either
Vadj (for commanded Voltage mode) or Iadj (for commanded Current mode). Message M1
on the display will verify that the controlled power supply is commanded to Voltage mode
(VM) or Current mode (CM). (Again, this command must be executed even if the display
originally showed the correct mode.)
6. If the controlled power supply is an M or MG Model, it is recommended that the voltage and
current values be reintroduced, even if the values shown are correct (If these values are
not set at this time and the output is disabled, then enabled, the output values will stay at
zero when the output is enabled.)
NOTE: When the controlled power supply is an M or MG Model, sending an output voltage or
output current parameter will cause the output to be enabled.
Set output voltage or voltage limit by pressing Vadj, entering the numeric value, and press-
ing ENTER; set output current or current limit by pressing Iadj, entering the numeric value,
and pressing ENTER.
7. To end the remote controlling operation press MENU ON/OFF; the unit will return to Menu
level with the display reading “Remote Channel.” Press MENU ON/OFF again to exit the
Menu.
3.2.2.4 CALIBRATION
1. Press MENU ON/OFF to enter the Menu, then press NEXT until “Calibration” is dis-
played; press ENTER to select this function.
2. The steps on the display guide you through the calibration procedure (refer to PAR. 5.5 for
details). Press NEXT to advance to the next step of the procedure.
3. Once “End of Calibration” screen is reached, press either NEXT or MENU ON/OFF
keys to return to menu. Press MENU ON/OFF again to exit the menu system.
3.2.2.5 OVP, OCP SET-UP
This function is used to set Over-Voltage (OVP) and Over-Current (OCP) protection values. The
unit will not allow programmed values or actual outputs above these limits.
