4.0 Operation of the EX-5100
It is best to have the EX - 5100 transmitters powered up and operational for 24 hours before applying calibration or test gas to
them.
When the EX - 5100 transmitter 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.
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 4.1.2 below.
