2) When open circuit or waveform distortion occurs in current output, the alarm light of
current open circuit on the front panel will turn on.
3) Pause control function (PAUSE). The pause button on the front panel can cut off the

4.3 High Power Output
With high power control button depressed, after several seconds, the high power control
button light will turn on. By then the current amplifier can improve 20% of output power.
This button can be used in case there have high current output needed and heavy load
applied.
Note:
1. Generally it’s not necessary to activate the high power output function, because it may
cause extra heat generated from amplifier.
2. High power output function must be inactivated as soon as the job was done. Never let
amplifier stay in high power output state for a long time.
3. Never apply the high power output function when output terminals are directly short
connected.
