Track
You can set channel 1 (CH1) and channel 2 (CH2), CH2 and Channel 3 (CH3), and all three channels
to tracking mode. When CH1/CH2 tracking is on, channel 1 and channel 2 respond relative to one
another when adjustments in voltage are made. A constant ratio is maintained between the voltage
settings on the two channels.
The voltage ratio is set between channel 1 and channel 2 when CH1/CH2 tracking is turned on. For
example, if channel 1 and channel 2 are both set to 1 V when tracking is turned on, a one-to-one ratio
is maintained and any voltage change on channel 1 results in a corresponding change on channel 2.
If channel 1 is set to 10 V and channel 2 is set to 5 V when tracking is turned on, a two to one ratio is
maintained and any voltage change on channel 1 results in a voltage change of half the size of
channel 2.
To set up CH1/CH2 tracking mode:
1. Press the
CH1
key.
2. Press the
V-Set
key and enter the voltage value for channel 1. For example, set the voltage of
channel 1 to 3 V.
3. Press the
Enter
key.
4. Press the
CH2
key.
5. Press the
V-Set
key and enter a voltage in the ratio you want for channel 2. For example, set the
voltage of channel 2 to 6 V. The ratio is 2.
6. Press the
Enter
key.
7. Press the
Menu
key, and using the down arrow key, navigate to
Track
, and then press the
Enter
key.
8. Press the down arrow key to select
Track CH1/CH2
and then press the
Enter
key to turn on
tracking.
9. Verify that
T
is displayed between the voltage readings of channel 1 and channel 2 on the
display. This indicates that the power supply is in tracking mode.
To set up CH2/CH3 tracking mode:
1. Press the
CH2
key.
2. Press the
V-Set
key and enter the voltage value for channel 2. For example, set the voltage of
channel 2 to 3 V.
3. Press the
Enter
key.
4. Press the
CH3
key.
5. Press the
V-Se
t key and enter a voltage in the ratio you want for channel 3. For example, set the
voltage of channel 3 to 6 V. The ratio is 2.
6. Press the
Enter
key.
7. Press the
Menu
key, and using the down arrow key, navigate to
Track
, and then press the
Enter
key.
8. Press the down arrow key to select
Track CH2/CH3
and then press the
Enter
key to turn on
tracking.
9. Verify that
T
is displayed between the voltage readings of channel 2 and channel 3 on the
display. This indicates that the power supply is in tracking mode.
