PURGE MODE
(OPTIONAL)
NOTE: This feature is for purging lines in and out of service only
(purging with line gas)
To conduct a PURGE:
To enter the PURGE mode from the work display, press and release the
TICK/MENU (B) button. Press and release the SAVE/ZERO (C) button
until PURGE is displayed on the bottom of the screen.
Press and release the TICK/MENU (B) button. PURGE TEST will be
displayed on the top of the screen with %v/v on the bottom left side of the
screen and O2 % on the bottom right side of the screen. If O2 (oxygen) is
not installed, an “X” will appear.
Attach a purge probe. Do not create a tight seal where the purge probe
is inserted for sampling. Allow for blow by so the unit does not get over
pressurized.
The LEL sensor is turned off during this mode to prevent unnecessary
exposure to high levels of gas for an extended period time. The O2
readings (if equipped) will reflect the amount of oxygen in the line.
To exit the PURGE mode, press and release the POWER/MUTE (A)
button to exit to the work display. A “Please Wait” message will flash (the
LEL sensor is being powered back on) and this message will appear for a
minimum of 5 seconds up to a maximum of 5 minutes.
