E2
Operators Manual
Operating the
E2
Operation of the
D2
is very straightforward, but there are a few points worth noting
which, once understood, will make using the unit even easier.
Switching the unit on and start-up procedure
After plugging in the power and switching the power on suing the rear panel switch,
confirmation is quickly given that all is well by all LEDs illuminating almost
immediately after power-up.
The LEDs of all ‘engaged’ keys (when the unit was last powered up) will illuminated,
and after the bypass relays disengage, a pattern will undulate across the LEDs as the
level fades up. The entire process is complete when the input/output meters begin to
operate normally. This whole start-up procedure only takes a few seconds.
Minimum and maximum control positions
To ensure that the
E2
is 100%
accurate all of the time, and that what
it says on the front panel is exactly
what the unit is doing, it has been
necessary to introduce ‘end-stops’ on
the controls.
The extreme regions on each control
marked with the curved line designate
this entire region as relating to the
parameter value shown. This is to
compensate for the mechanical
tolerances of the potentiometers.
