Low Battery Warning
A battery warning will occur when the internal Lithium Iron Phosphate battery voltage
becomes low
(Figure 31) . You can either continue working or connect the 12V AC Power
Supply and continue to work by pressing ‘IGNORE. The analyzer will charge the battery
while it is connected to the AC Power Supply but if you wish to use it wirelessly press
‘OFF’,
plug the analyzer into the AC Power Supply via the 12DC Outlet Input on the Back Panel and
allow it to fully charge. Full charge will take at least 2 hours.
3.7
Air Sensor Low
In the event you receive an ‘Air Sensor Low’ message like
(Figure 32) there is no need to
discontinue use. This message is meant to alert you that the built-in oxygen sensor is
depleting and will need to be replaced in the near future. If the analyzer you are using is new
and you believe you received this message in fault, first verify gas is not flowing into the
analyzer and that you are in a well-ventilated area. Once you have verified both, press
‘RECAL’ to recalibrate the analyzer. If you have had the analyzer for a few years the oxygen
sensor may be near
depletion. Pressing ‘TEST’ allows you to bypass the message and finish
your testing. The oxygen sensor is a consumable part and will eventually need to be
replaced. After receiving this message plan on contacting Ritchie Engineering to schedule a
service appointment.
3.8
Error Messages
In the unlikely event that an “Error” message is displayed on the screen, power off the unit,
take it to a location outside of the shop environment where fresh air is available and turn the
unit back on. If the “Error” message reappears, refer to the help screens on the instrument or
contact our service department for assistance.
