Illustration of the display, showing the value 0.314

The panel meter is the LCD display unit located in the lower right on the upper PCB.

Usage

Depending on the position of the MODE SELECTOR knob, the panel meter is used to monitor either values or OP-TIMEs (operation times):

Monitoring Values

With the MODE SELECTOR knob in the COEFF, MINION, IC, OP or HALT positions, the panel meter displays values numerically in the unit range -1 to 1.

  • With the MODE SELECTOR knob in the COEFF position, the panel meter displays the output value of the COEFF potentiometer selected using the COEFFICIENT SELECTOR. This allows setting the values of coefficient potentiometers to their desired values.
  • With the MODE SELECTOR knob in the MINION, IC, OP or HALT positions, the panel meter displays the value patched into the U socket in the OUTPUT JACKS section. This allows monitoring the values of arbitrary positions on the patch panel.


Monitoring OP-TIMEs

With the MODE SELECTOR knob in the REP or REPF positions, the panel meter displays the current OP TIME, which can be changed by turning the OP-TIME POTENTIOMETER.

  • With the MODE SELECTOR knob in the REP position (i.e., in repeat mode), the OP TIME is shown in the 0 to 10 second range.
  • With the MODE SELECTOR knob in the REPF position (i.e., in repeat fast mode), the OP TIME is shown in the 0 to 100 millisecond range.
