Diagnostics
Basic faults or diagnostics are presented as symbols. Should a fault occur most can
be corrected by pressing ENTER or ESC to clear the fault message. All fault
conditions cause the TIGER to alarm.
Pump failure
Pump blocked or pump failure
The flow of gas through the instrument has fallen below 100
cc/minute. Check the probe and filter for signs of blockage.
Water or dirt in the probe, a bent probe, dirty filter on the
inlet or blockage of the exhaust (finger over hole on the
back?) can all cause low flow. If the blockage can be
removed, press Escape to clear the alarm. If the fault
persists send the instrument to your distributor for service.
Battery dead
Battery low or battery failure
The Tiger will shut down when the battery level falls below
2%. Recharge the battery as instructed on page 29 of this
manual ensuring that all connections are sound and the
indicator lights on the charger are in order. If the battery
fails to charge, fit another battery pack if available. If using
alkaline batteries, replace them. If the fault persists send
the instrument and charger to your distributor for service.
Lamp out
Lamp failure
The PID lamp has failed to strike (illuminate); this may
occur at switch on or during use. Switch the TIGER off and
replace the lamp. See Maintenance page 35.
Memory full
Memory cannot receive more data
The data log memory is full. This will only happen if the Log
Full box is set to
„alarm‟ on the TIGER PC configuration
screen. Press the Escape key to continue, but the TIGER
will no longer continue to log data. Select „recycle‟ in
TIGER PC and the TIGER will overwrite the oldest data and
no alarm will be raised.
System error
Total system failure
The instrument‟s firmware is corrupted. In the unlikely
event of this message appearing, contact Ion Science or
your nearest authorised service centre.
