Note: The “Nitrowatch” mode allows operation of the RH sensor with Terra’s NitroWatch® low-humidity

controller. In this mode, a HIGH R/H alarm is activated when the R/H input is above the set point.

2.13 bEEP The display will indicate “bEEP” until the set button is released. The display will indicate “on” or “off.”

Use the UP and DOWN buttons to change this value. ON indicates that the beeper will be activated

when an alarm occurs. OFF indicates that the beeper is disabled. Press the SET button to finish and

move to the next parameter.

2.14 Hu The display will indicate “hU” until the set button is released. Use the UP and DOWN

buttons to change the displayed value: ON indicates HUMEX mode (humidification); OFF

indicates NITROWATCH mode (dehumidification).

2.15 Add The display will indicate a supplemental value that the Humex will “Add” to the measured

RH. This value adjusts the R/H reading to allow manual calibration to an independent

humidity sensor or calibration device. Use the UP and DOWN buttons to set this value,

which can be positive or negative. Press the SET button to finish and exit the setup mode.

Note: the “Add” value will wrap around if the maximum or minimum value is exceeded. For example,

if you try to set the supplemental adjustment value above 49.5, the value will wrap around to -50.

A side effect of using an adjust value other than zero is that the R/H range will be reduced. For

example, if the adjust value is -10, then the maximum R/H value that can occur is 90 because the

input value (100) will be added to the adjust value before the system uses it.

2.16 Alr The display will indicate “Alr” until the set button is released. This is the

MINUTES/SECONDS selector for the alarm timers. Use the UP and DOWN buttons to

change this setting. The display will indicate “Long” for MINUTES and “SHrt” for

SECONDS. Press the SET button to finish.

Press SET once more to advance to Normal Run Mode. You should view the current %RH level inside

the glove box.

Make a mistake? No Problem!

To reset the system, turn the system OFF while in setup mode and restart while holding the SET button.

Humex 2™ Operation

After completing the set-up programming steps above, enter SET to view the current % RH set point. Use

the UP/DOWN keys to change this value. Press SET again to return to Normal Run Mode and view

current % RH.

Beeper Silencing – Press any front panel button to silence the beeper during an alarm condition.

The Humex 2™ will now turn ON a low flow of water and activate the heater to introduce water vapor

into the glove box whenever the % RH falls below the set point. When the set point is attained, this

moisture flow is terminated.
