Cause / Remedy
Batteries are probably dead or incorrectly fitted. Check you
have fresh batteries fitted and that they are inserted the
correct way round.
Batteries are probably nearly dead or incorrectly fitted. Check
you have fresh batteries fitted and that they are inserted the
correct way round.
Probably a poor connection. Switch the Macro 900 Meter off,
disconnect the Macro Accessory Probe, ensure there is no
debris or moisture in the plugs and sockets, then re-connect
ensuring they are fully inserted and that the screw collars are
fully tightened.
The Macro 900 Meter probably does not have a good enough
view
of
the
available
obstructions between the Macro 900 Meter and the open sky.
Remember, GPS does not work indoors.
The USB drivers may not be properly installed. Reinstall the
USB drivers carefully following the instructions.
There may be a problem with the USB socket on the PC, try an
alternative socket.
The batteries in the Macro 900 Meter may be dead or
incorrectly fitted. Check you have fresh batteries fitted and
that they are inserted the correct way round. The USB cable
does not power the Macro 900 Meter.
There may be a problem with the USB socket on the PC, try an
alternative socket.
This indicates that the pH electrode has dropped below 85%
efficiency. Try cleaning the pH electrode and re-calibrating as
described in the relevant section of this manual. If that does
not cure the problem, replace the electrode.
This indicates that the Optical DO electrode needs calibrating
or the cap needs replacing. Perform a full DO calibration, first
at DO Zero then at 100% DO. If that does not cure the
problem, replace the Optical DO Cap
This indicates that the MAP has stopped responding to requests
for data from the Macro 900 Meter. Check the MAP plug is fully
inserted. Restart the meter to reset the MAP.
Remove and discard the batteries immediately. Thoroughly
clean the battery compartment and terminals. If the battery
terminals are corroded, contact our Service Department for
return instructions.
The DO electrode may need calibrating. Recalibrate.
The DO membrane may be dirty. Clean the DO membrane.
Calibration may have been carried out at an extreme
temperature. Recalibrate at a temperature as close to the
sample temperature as possible.
