Temperature and Other are also available. Default is
NH3.
Press the key to highlight the gas type, and then
use the / arrow keys to make the selection. Then
press
ENT
to accept or
ESC
to exit without saving.
Note : If "OTHER" is chosen, press the key to get the
flashing cursor for a custom label. Use the keys

Units
Select unit of measurement. Default is PPM.
# of Decimal Points
Select number of decimal points displayed on the LCD.
Typically, a full-scale range of 100 or greater will have
0 decimal places.
4 mA
Select zero value. For most gas detectors, 4 mA will
be equal to "0" ppm. A few examples of when the the
values are not 0 are oxygen sensors ranged 15 to 25%
(4 mA = 15) and temperature sensors ranged -60 to
150 (4 mA = -60).
Use the keys to set the value, then press the
ENT
key to save it.
20 mA
Select the full-scale value. For example, a gas detector
ranged 0.00-1.00% will have a full-scale value of 1.00
(20 mA = 1.00). 1.00% can also be displayed as 10000
ppm, whichever is preferred.
Use the keys to set the value, then press the
ENT
key to save it.
Alarm Setpoint
The EM2 has one alarm relay output. Use this field
to select the value of the alarm setpoint. The alarm
setpoint can only be set between 5% and 100% of
full-scale.
