Lamp
Enables the selection of different lamp types you may have
purchased to use with your instrument.
If you have purchased the instrument with the 11.7eV lamp,
there are a number of things related to applications that you
must take into consideration before using the lamp.
1. It is important for the lamps to be stored in their
desiccated vials in cool
conditions (15-25°C).
2. The lamps should
-
Chemically
containing significant concentrations of acids and strong
solvents such as dichloromethane.
-
Conditions of condensing humidity; always dry cool air through the
instrument before storage. For long storage periods, remove the lamp and return it to the desiccated vial.
-
Physically severe environments: large temperature changes may initiate
lamp failure.
Application
Enables the selection and de-selection of Health & Safety mode and the selection of ppm, ppb or mg/m
Health & Safety mode, STEL and TWA timings can be adjusted to reflect the changes in legislation between
the US and Europe.
The instrument can be set to security mode, which enables the locking of the user interface so that the
instrument functions can not be changed manually. To de-select security mode, switch the instrument OFF
then ON, you then have 2 minutes from switch on to connect your instrument to a PC and select INSTRUMENT
/ MENU SET UP. This will automatically place your instrument in PC mode ready for download or further
adjustment. VOC smoothing relates to the PID reading and is used to have a dampening affect on the
measurements for high gain factor gases. In effect, increasing the T90 time to create a smoother graph. This
affect can only be applied when in Survey mode; it does not apply in Heath & Safety Mode. Lastly there's the
option of choosing type of readout you get from the instrument with regard to the LEL sensor. %LEL shows
the readout as a percentage of the lower explosive limit whereas %VOL shows the readout as a percentage
volume of the gas in the air.
