Back-light (P1000, 2000, 3000 & 5000)
The instrument display can be illuminated when in low light
conditions. When On is selected the back-light is on when ever
the instrument is switched on. When Off is selected the back-light is permanently off.
When Timed is selected the back-light illuminates for a pre-set time after every key
press. When timed is selected pressing enter allows the user to adjust the on time
from 1 to 60 seconds. This menu options is also available on the IONpc software.
Date / Time (P2000, 3000 & 5000)
The Date / Time function allows the adjustment of the time and
date used within the P internal clock. The internal
clock is used for the data logging date / time stamp. When readings are being stored
for download and future use and record keeping ensure that the clock and date are accurately set.
The 12/24 hour time format is also adjustable. Ion Science recommends that you set your date and time
before using your instrument for the first time. This menu options is also available on the IONpc software.
PID Gas Selection (P1000, 2000, 3000 & 5000)
The P photo ionisation detector (PID) is non-selective. Although
many VOC gases are detectable, the P PID cannot differentiate
between the gases. When you select the VOC gas you wish to measure from the P internal
gas list, the instrument will calculate the equivalent level for that selected gas against an isobutylene
calibration. Please note that there may be other detectable gases present that may effect the
measurement.
Custom
offers a quick route to the last 10 selected gases. When selected, use the UP
and DOWN keys to change the gas then press ENTER to select.
List
allows selection of any gas from within the gas table held in the P
memory.
After selecting the List symbol, select the first letter of the gas you wish to select and
press ENTER. The P will then list all gases starting with that letter. WMD
gases are prefixed with the letters WMD.
Alarm levels that are set in the Gas table will be automatically selected. Should a gas be
selected that is not compatible with the selected lamp the following symbol will appear
to highlight the incompatibility.
PID Lamp (P1000, 2000, 3000 & 5000)
An alternative lamp to the Krypton 10.6eV (standard) can be
purchased, fitted and selected. A tick '
' confirms the selection.
Should a Lamp be selected that is not compatible with the selected
gas the following symbol will appear to highlight the incompatibility. This menu
option is also available on the IONpc software.
