R e m o t e c o n t r o l
to local mode (permitting operation using the front
panel controls).
MX1 + MX0
Format: MX1
Function: Switches the power supply from remote mode into
mixed mode. In mixed mode, the instrument can be
operated either by interface or using the frontpanel
controls.
Format: MX0
Function: Terminates mixed mode and returns the instrument
to remote mode.
SU1 + SU2
Format: SU1:VV.mVmV or SU2:01.34
SU1:VV.mVmV or SU2:01.34
Function: Sets voltage 1 or voltage 2 to the indicated value (SET
value; BCD format)
Example: SU1:1.23
→
SU2:12.34
→
SI1 + SI2
Format: SI1:A.mAmAmA or SI1:0.123
SI1:A.mAmAmA or SI1:0.123
Function: Sets current limit 1 or current limit 2 to the indicated
value (LIMIT value; BCD format)
Examples: SI1:1.000
→
SI2:0.123
→
RU1 + RU2
Format: RU1 or RU2
Reply: U1:12.34V or U2:12.34V
Function: The voltage values sent back by the HM8143 are the
programmed voltage values. Use the MUx commands
to query the actual values.
RI1 + RI2
Format: RI1 or RI2
Reply: I1:+1.000A or I2:–0.012A
Function: The current values sent back by the HM8143 represent
the programmed limit values for the current. Use the
MIx commands to query the actual current values.
MU1 + MU2
Format: MU1 or MU2
Reply: U1:12.34V or U2:12.24V
Function: The voltage values sent back by the HM8143 represent
the actual voltage values last measured at the outputs.
Use the RUx commands to query the voltage values
set.
MI1 + MI2
Format: M11 or M12
Reply: I1=+1.000A or I2=–0.123A
Function: The current values sent back by the HM8143 represent
the actual current values last measured. Use the RIx
commands to query the programmed current limit
value. If the outputs are switched off, then the reply
will be I1: 0.000 A.
TRU
Format: TRU:VV.mVmV
TRU:VV.mVmV
Function: Sets voltage 1 and voltage 2 to the indicated value
(voltage values in TRACKING mode). The values must
follow the BCD format.
Examples: TRU:1.23
→
TRU:01.23
→
TRU:12.34
→

Subject to change without notice
U1 = 1.23 V
U2 = 12.34 V
I1 = 1.000 A
I2 = 0.123 A
U1 = U2 = 1.23 V
U1 = U2 = 1.23 V
U1 = U2 = 12.34 V
TRI
Format: TRI:A.mAmAmA
TRI:A.mAmAmA
Function: Sets current 1 and current 2 to the indicated value
(LIMIT values in TRACKING mode). The values must
follow the BCD format.
Examples: TRI:1.000
→
TRI:0.123
→
STA
Format: STA
STA?
Reply: OP1/0 CV1/CC1 CV2/CC2 RM0/1
Function: This command causes the HM8143 to send a text-string
containing information of the actual status.
OP0 The outputs are switched off.
OP1 The outputs are switched on.
CV1 Source 1: constant voltage operation
CC1 Source 1: constant current operation
CV2 Source 2: constant voltage operation
CC2 Source 2: constant current operation
RMI Device in remote control mode
RM0 Device not in remotecontrol mode
Example: If the outputs are on, the HM8143 answers for
example with the following string (channel I is in
constant voltage mode and channel II is in constant
current mode:
OP1 CV1 CC2 RM1
If the outputs are off, the answer string contains
instead of the status of channels I and II two times
three dashes (––– –––).
OP0 ––– ––– RM1
OP1 + OP0
Format: OP1
Function: The outputs are switched on.
Format: OP0
Function: The outputs are switched off.
SF + CF
Format: SF
Funktion: Activation of the electronic fuse.
(Set fuse)
Format: CF
Funktion: De-activation of the electronic fuse.
(Clear fuse)
Clear
Format: CLR
Function: This command interrupts all functions of the HM8143.
The outputs are switched off, the voltages and cur-
rents are set to 0.
VER
Format: VER
Reply: x.xx
Function: Displays the software version of HM8143.
Example: 1.15
ID?
Format: ID?
*IDN?
Reply: HAMEG Instruments, HM8143,x.xx
Function: HAMEG device identification
Example: HAMEG Instruments, HM8143,1.15
I1 = I2 = 1.000 A
I1 = I2 = 0.123 A
