User Keys - Gray with Black Letters
The four keys with black letters provide the user 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. The user should have qualified personal
determine the problem with the unit.
RESET Key
The RESET key performs two functions. 1) Resets the alarm light, alarm
contacts, and audible alarm when in a latched or non automatic reset mode. The
room pressure must be in the safe or normal range before the
RESET key will
operate. 2) 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 the user (see MUTE TIMEOUT ). When
the mute period ends, the audible alarm turns back on if the alarm condition is
still present.
NOTE : The user can program the audible alarm to be permanently turned off
(see AUDIBLE ALM ).
AUX Key
The AUX key is active only in specialty applications and is not used on the
standard SureFlow monitor. If the AUX key is used, a separate manual
supplement will explain the AUX key function.

The four keys with blue print are used to program or configure the unit to fit a particular
application.

key acts as an escape key to remove you from an item or menu, without saving

MENU key is further
described in the Software Programming section of this manual.
