2.3 Monitor
The monitor has a 5-digit display, set-up on delivery to display a dew-point temperature
range of -100° to +20°Cdp (-148° to +68°Fdp).
Dew-point temperature units are displayed by the last LED located to the far right of
the display. On delivery, °Cdp is set-up. If required, the units can be changed to °F. The
method of confi guring the unit for °F is described in Section 3.2.
Optionally, the instrument can be set-up to read moisture content in parts per million
(ppmV), pounds per million standard cubic feet (lbs/MMSCF) or grams per cubic meter
(g/m3). This option requires the hygrometer to be set-up as detailed in Section 3.2.
Four alarm indications are provided by four LEDs located on the bottom of the display.
These are marked SP1, SP2, SP3, SP4. Access to the alarm relay contacts is provided
on the rear panel. The connection for these alarm relay contacts is shown in
Figure 15
