The Red LED's will illuminate at higher levels of gas and the tic rate will increase to become al-
most continuous. Rotate the thumb wheel anti clockwise to reduce the tic rate, resetting the
ROTEST Electronic 4 to the new background level. Move the ROTEST Electronic 4 tip into
higher concentrations of gas (indicated by the increased tic rate and illumination of the yellow
and red LED's until the leak is found.
The tip light is activated by pressing the light/mute button
once more.
To mute the tic sound press and hold the light/mute button
and hold the mute button again.
To pin-point a gas leak:
After completing the warm up period in fresh air, move the tip of the ROTEST Electronic 4
"wand" towards the suspected gas leak. The tic rate and LED flashing will increase as the con-
centration of the gas increases, thereby leading you to the gas leak.
If the Red LED is illuminated and the tic is continuous before you have pin-pointed the gas leak,
you must reset the ROTEST Electronic 4 in this concentration of gas. To do this, rotate the
thumb wheel anti clockwise to reduce the tic rate, resetting the ROTEST Electronic 4 to the new
background level. Move the ROTEST Electronic 4 tip into higher concentrations of gas (indicat-
ed by the increased tic rate and illumination of the yellow and red LEDs until the leak is found.
Tips:
If the initial tic rate does not settle to once every two seconds, switch off and back on to allow
additional re-setting time.
The ROTEST may be reset at any time by switching off and back on.
The ROTEST will detect methane and most other "HC" gases down to low ppm levels.
Some leak detection fluids can cause a (temporary) false indication. Use the ROTEST
Electronic 4 first!
The ROTEST Electronic 4 is intended for use in sheltered areas or indoors as severe draughts
may cause (temporary) false indication.
Avoid contamination by water or dirt and do not allow any reactive chemicals etc. to come in to
contact with the sensor.
