4.0 Operation
4.1 Start Up SE-5175
When the SE-5175 is first powered up, it goes through a series of momentary screens, which identify the instrument model
number, serial number and software revision. After all of the momentary screens have been displayed, the instrument arrives at
the Main Gas Display showing the gas concentration and unit of measurement, the POWER green LED is on and the red alarm
and fault LEDs are not lit.
Depending on transmitter configuration and calibration condition, the furthest right character in the display may flash a letter
indicating the instrument status. See the Section 4.1.1 below.
4.1.1 Typical Start Up
When power is supplied to the SE-5175, the instrument will display the following sequence of information:

5.2 SE-5175 Maintenance Adjustments
Calibration of the SE-5175
Calibration is the process of setting the instrument up to read accurately when exposed to the target gas. The Zero function sets
the clean air reference point and the Span function sets the sensitivity of the instrument.
Initial Calibration: Wait 3 – 4 hours after initially supplying power to the SE-5175 instrument before initial calibration. The
SE-5175 has been precalibrated at the factory, and initial field calibration should result in only fine tuning to circuit, as well as
a way to check that installation is successful. It is not necessary to open the enclosure to make adjustment. The calibration
functions are operated with pushbuttons from outside the enclosure through the
Calibration Zero and Span functions are two separate procedures. They operate independently of each other. It is
recommended that the Zero procedure be done prior to the Span procedure.
N
OTE
: Zero function is not used for Oxygen transmitters.
ENMET Corporation recommends at least quarterly calibration of the SE-5175 instrument.
Calibration equipment is available from ENMET Corporation to calibrate the SE-5175 instrument.
•Calibration adapter, a length of tubing with a regulator for the gas cylinder on one end, and a fitting to connect to the SE-
5175 sensor/transmitter on the other.
•Gas cylinder, Zero gas 20.9% oxygen or Span gas, typical 50% of instrument full scale.
Generally, a cylinder of 20.9% Oxygen is used to provide a Zero point or fresh air reference for the calibration.
