Illustration of Bi-Polar Tracking Mode
4.5. Setting Parallel Tracking Mode
1. Press both TRACKING MODE SLECTION KEY [9,12] to enable parallel tracking mode .In
parallel tracking mode, CH2 output voltage and current value follows CH1 setting. The output
current is double to the CH1 display value.

2. Use CH1 VOLTAGE KNOB [14] to adjust the desired voltage output value.
3. CH1 CURRENT KNOB[15] adjust the desired current output value.(Reference to Section 4.2)
4. Connect the circuit to the CH1 TERMINAL [18,19] to get double current output.
4.6. Caution!
5 V output has reliable protection for current-limit and short. The two adjustable outputs have
current-limit protection. As there is controlling circuit for regulating transistor’s power loss in the
circuit, when short-circuit occurs, the power loss on large power transistors is not very high, it can’t
cause any damage to the unit. But there is still power loss when short-circuit, in order to reduce
aging and energy consumption, so this situation should be find as soon as possible and turn off
power, then exclude the faults.
When operating is finished, put it in a dry place of good ventilation, and keep it clean. If it is not in
use for a long period, pull off the power supply plug for storage.
For maintenance, input voltage must be cut off.
