Chapter 3: Basic Operations 29
NOTE: The two fi elds, Converted minimum value and Converted maximum value, enable you
to input a conversion range used to mathematically convert an input value from its input range
to the conversion range. The EVR1500 environmental monitor provides linear conversion
between these values. For example, for a temperature probe with a range of Ø to 5 VDC and
a conversion range of -40 to 85 degrees C (Celsius), 1 VDC would be equal to -40 degrees C
and 5 VDC would be equal to +85 degrees C.
9. In the Units for converted value fi eld, type the unit you wish to display
with the value (for example, degrees F or degrees C).

Configuring Digital Outputs
After installing the EVR1500 environmental monitor appliance and configuring
the network, you can configure and rename two digital outputs (plug-in
modules 7 and 8) through the Configuration tab interface.
The front panel LEDs (Audio_LED, Air_Flow_LED, Humidity_LED,
Temperature_LED) also display in the Digital Outputs window and are
defaulted to green [Current Value = 1 (green) or Ø (red)]. Refer to Setting
Thresholds and Configuring Rules in Chapter 4 for instructions on configuring
the front panel LEDs.
NOTE: The Heater_Control digital output is used to eliminate excessive condensation from the
internal humidity sensor. The default value is Ø or Off. Setting the value to 1 or On for 30 to 60
seconds eliminates condensation.
