<Precautions>
・
Input an absolute value without the negative sign in the place of
＊＊＊＊
to change the channel
of negative output.
・
Some models do not have C channel and D channel. If a command for controlling the C channel
or D channel is sent to such a model, the command is invalid.
・
These commands may not change the voltage while the tracking function is activated.
The voltage may only be changed with the tracking voltage setting command (EA, EB, EC or ED).
・
These commands may not change the current while the tracking function is activated.
The current may only be changed with the tracking current setting command (IA, IB, IC or ID).
・
The PRESET 4 key of the PW-A power supply unit corresponds to the VARIABLE key of the PWR
power supply unit. Thus, VA, VB, VC, VD, AA, AB, AC and AD are the preset 4 setting
commands. In preset selection described in “9-7-12.”, PR0 is selects preset 4.
9-7-3. Activating or deactivating tracking function
TO0
／
TO1
・
The TO0 command turns off the tracking function. The TO1 command turns on the tracking
function. When the tracking function is activated (immediately after the TO1 command is
executed), the absolute value tracking mode is selected. Specify the correct tracking mode with
the TM command shown in “9-7-5.” and change the voltage and current.
<Precautions>
・
The tracking function will not be activated when all channels are set in the "non-tracking" status.

<Precautions>
・
The tracking function is turned off automatically when "no tracking" is specified for all outputs in
the tracking mode.
・
These commands are not accepted while the main output key is on.
9-7-5. Selecting tracking mode (voltage/current variation)
TM0
／
TM1
・
The TM0 command selects the absolute tracking mode. The TM1 command selects the
percentage tracking mode. When the tracking function is activated (immediately after the TO1
command is executed), the absolute tracking mode is selected. Specify the correct tracking
mode with the TM0 or TM1 command and change the values. These commands are executed
only when the tracking function is activated. (See section “9-7-3.”.)
