Remote control
MU1 + MU2
Format: MU1 or MU2
Reply: U1:12.34V or U2:12.24V
Function: The voltage values sent back by the HM8143 re-
present 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 re-
present the actual current values last measured.
Use the RIx commands to query the program-
med current limit value. If the outputs are swit-
ched 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 va-
lue (voltage values in TRACKING mode). The va-
lues must follow the BCD format.
Examples: TRU:1.23
TRU:01.23
TRU:12.34
TRI
Format: TRI:A.mAmAmA
TRI:A.mAmAmA
Function: Sets current 1 and current 2 to the indicated va-
lue (LIMIT values in TRACKING mode). The va-
lues 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 cons-
tant current mode:
OP1 CV1 CC2 RM1
32
U1 = U2 = 1.23 V
→
U1 = U2 = 1.23 V
→
U1 = U2 = 12.34 V
→
I1 = I2 = 1.000 A
→
I1 = I2 = 0.123 A
→
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 volta-
ges and currents 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

Arbitrary

The arbitrary waveform mode can be used for generation
of virtually any desired waveforms. For this purpose, a ta-
ble comprising up to 1024 voltage and time values (soft-
ware limitation) can be defined. This table is stored in non-
volatile memory with a backup battery, and is not lost for
several days when the instrument is powered down. The
following commands are available for operating and pro-
gramming this function by interface:
ABT Transfer of arbitrary values
RUN Start waveform generation
STP Stop waveform generation
Attention: The arbitrary waveform mode only effects the left
channel of the power supply; rapid waveform generation is possi-
ble with this channel only.
