Unplug the 12VDC power connector (phone jack). Hold down the SET button while reconnecting the 12VDC
connector to turn ON power to the Humex 2. The set button is the left-most button on the front control panel.
Repeatedly pressing SET will advance through these alarm displays. Use UP/DOWN buttons to change default
settings (show in parentheses). See steps below for more information on each setting.
DOOR Open Door Delay Alarm (60 seconds) – used only for multi-door cabinets with door sensor switches.
For glove boxes, a jumper is installed in the “Door Switch” port to deactivate this alarm.
rH Relative Humidity Set Point Alarm (60 seconds) – the number of seconds that the %RH level must be
below the humidity set point before alarm is activated.
bEEP Enables and disables beeper.
hU Humex/NitroWatch Alarm Mode – toggles back and forth between operation mode for Humex 2™
Humidifier and NitroWatch® Low-Humidity systems. When the “hU” mode is ON, the system activates
the rH alarm when the measured %RH level remains below the set point for the specified time
(appropriate to humidification applications). When the “hU” mode if OFF, the system activates the rH
alarm when the measured %RH level remains above the set point for the specified time (appropriate to
dehumidification applications).
Add Calibration Adjust Mode – adds a supplemental numerical value (positive or negative) to the measured
%RH to allow calibration of the device to an NIST-certified or other RH meter.
Alr Alarm Timers – lets you select minutes (“Long”) or seconds (“SHrt”) as the time scale for all alarm
functions.
Once you enter the SET mode, use these guidelines to change any defaults:
2.11. Door The display will indicate “door” until the set button is released. The value displayed is the

the UP and DOWN buttons to set this value. Press the SET button to finish and move to the next
parameter.
2.12 rH The display will indicate “rH” until the set button is released. The value displayed is the number of
seconds that the R/H input must be below the set point when in the Humex mode before a LOW RH
alarm will be activated. Use the UP and DOWN buttons to set this value. Press the SET button to finish
and move to the next parameter.
