User Keys - Gray with Black Letters
The four keys with black letters provide you information without changing the operation or the function of the unit.
TEST Key
The
TEST
key initiates an instrument self-test. Pressing the
TEST
key activates a scrolling sequence on
the display that shows the product model number, software version, and all set point and alarm values. The
unit then performs a self-test that tests the display, indicator lights, audible alarm, and internal electronics
to ensure they are operating properly. If a problem with the unit exists,
DATA ERROR
will be displayed.
You should have qualified personnel determine the problem with the unit.
RESET Key
The
RESET
key performs three functions. 1) Resets the alarm light, alarm contacts, and audible alarm
when in a latched or non-automatic reset mode. The DIM must return to the safe or normal range before
the
RESET
key will operate. 2) Resets the emergency function after the emergency key has been pressed
(see
EMERGENCY
key). 3) Clears any displayed error messages.
MUTE Key
The
MUTE
key temporarily silences the audible alarm. The time the alarm is temporarily silenced is
programmable by you (see

). When the mute period ends, the audible alarm turns back
on if the alarm condition is still present.
NOTE
: You can program the audible alarm to be permanently turned off (see
AUDIBLE
ALM
).
