6-4. Tracking Function
・
The tracking function changes the current or voltage of several channels simultaneously.
Two modes are available: Absolute value change mode, and percent change mode.
In the absolute value change mode, the set values of channels are changed in numeric values.
In the percent change mode, the set values are changed in percentage, regarding the value when
tracking operation is turned on as 100%.
・
It is also possible to tracking and - tracking. The + tracking increases values when the
rotary encoder is rotated clockwise. The - tracking decreases them when the rotary encoder is
rotated clockwise.
・
In the percent tracking mode, the set value is displayed between 0% to 200%.
However, when the DISPLAY/STATUS key of negative output is selected, "-" is kept displayed.
※
For details of the tracking function, see Figs.10 and 11.

Operation procedures
1. Press the STATUS key twice when the MAIN OUTPUT key is off. The characters "trAc" are
displayed on the current indicator.
2. Press the DISPLAY/STATUS key of a channel to be tracking-controlled. The LED of the key is lit
in green. (Every time the key is pressed, the LED goes out, is lit in green, lit in red, and goes out
in this sequence.) A channel with the LED lit in green is controlled in the positive tracking mode.
A channel with the LED lit in red is controlled in the negative tracking mode. Tracking is not
executed when a single channel is selected. Select several channels and turn on their LEDs.
Channels whose LEDs are lit are selected for tracking.
Operation of the DISPLAY/STATUS key carried out here is not reflected upon the normal operation.
3. Press the STATUS key to turn on the voltage and current indicators. Tracking operation setting
of each channel is stored.
<Precautions>
・
No channel may be selected for tracking when the MAIN OUTPUT key is on.
6-4-2. Selecting tracking mode
・
Press the TRACKING ON/OFF key. The LED of the key is lit up in green.
Every time the TRACKING abs( )/% key is pressed in this condition, the LED of the TRACKING
abs( )/% key goes out and is lit up in green alternately. When the LED of the TRACKING
abs( )/% key is lit up in green, the absolute value tracking mode is selected. When the LED of
the TRACKING abs( )/% key is off, the percentage tracking mode is selected.
※
See Figs.10 and 11 for the variation in the tracking mode.
