followed by

n =

node address of the controlled power supply

M1 = message showing the commanded mode of operation for the controlled power sup-

ply:

VM — Voltage Mode

CM — Current Mode

— Voltage Limit: indicates that the controlled power supply was commanded to

be in Current mode but the load is forcing it to operate in Voltage mode.

CL — Current Limit: indicates that the controlled power supply was commanded to

be in Voltage mode, but the load is forcing it to operate in Current mode.

M2 = message showing the commanded polarity of the controlled power supply:

P+ — Polarity plus (non-reversed)

P-

— Polarity minus (reversed) (available on MR and MGR Models only)

M3 = message showing the commanded output status of the controlled power supply:

OD — Output Disabled

OE — Output Enabled

***V

and

***A

indicate the output values of the controlled power supply:

If the controlled MBT power supply is an M or MG Model, this represents actual output
values of the controlled power supply. (When output is disabled, 0V and 0A are the
true outputs.)

If the controlled MBT power supply is an MR or MGR Model, this represents actual
output values of the controlled power supply if the output is enabled; if the output is
disabled, this represents the internal output of the controlled power supply since the
load will either be isolated (commanded Voltage mode) or short-circuited (com-
manded Current mode). The display will show programmed voltage and 0A for com-
manded Voltage mode, and 0V and programmed current for commanded Current
mode.

#n M1; M2; M3

NOTE: A blinking “:” is represented by “ ” to

indicate that the values displayed on
the bottom line of the alphanumeric
display are “live,” i.e., actual values at
the power supply output.

***V ***A

NOTE: the status LEDs above the dis-

play reflect the actual status of
the controlling power supply,
not the settings of the con-
trolled power supply.
