Error Codes
The internal variables %In and %Rn are not available for the ACH,
VAR, and VAR? commands. Do not use the internal variables for the
commands.
200 Channel output switch must be ON.
To enter the specified command, set the channel output switch to ON.
201 Compliance must be set.
To change the source output mode (voltage or current), set the
co
mpliance value.
202 Interlock
circuit must be closed.
To set the output voltage or the voltage compli
ance to more than ±42 V
(high voltage state), close the interlock circuit. If the interlock circuit is
opened in the high voltage state, outputs of all units will be set to 0 V.
203 Cannot enable channel.
The channel output switch cannot be set to ON in the high voltage state.
Set the outp
ut voltage or the voltage compliance to ±42 V or less to set
the switch to ON.
204 Cannot disable channel.
The channel output switch cannot be set to OFF in the high voltage
state. Set the o
utput voltage or the voltage compliance to ±42 V or less
to set the switch to OFF. Or send the CL command with no parameter to
set switches of all channels to OFF immediately.
205 DZ must be sent before RZ.
The RZ command is effective for the channels set to
0 V output by the
DZ command.
206 Do not specify the channel recovered by RZ.
Specify the channels that have not been recovered yet by the RZ
command after the DZ command.
The RZ command cannot be
executed if the specified channels include a channel that has already
been recovered by the RZ command.
210 Ext trigger could not start measurement.
External trigger cannot start measurement because of bus
y condition.
211 TM1 must be sent to use GET.
