the input. When this error exists you will not be able to perform any programming or configuration of the transmitter until the issue is 

resolved. The “OFL” or “UFL” condition can be due to a variety of possible causes which are summarized below:

POTENTIAL TEMPERATURE INPUT RELATED PROBLEMS:

• 

A temperature element is not properly connected to the transmitter input board. Most electrochemical transmitters require a valid 

temperature input in order to operate properly, and this general rule is also true for the TT-MA transmitter.

 

o

Check that each of leads are firmly connected to the proper terminals per the wiring schematic.

 

o

If no sensor is available or the sensor employed does not have a temperature compensation element, please use a 110 Ohm axial 

resistor to simulate a P100 TC input @ 25°C or a 1100 Ohm axial resistor to simulate a Pt1000TC input at 25°C.

 

o

Even when using manual temperature compensation mode it is best practice to employ a simulation resistor on the TTMA 

transmitter. Such a simulation resistor can be supplied free of charge from the factory if requested prior to dispatch of the order.

• 

Check the transmitter setting for the Pt100/Pt1000 TC type matches the temperature element in sensor.

POTENTIAL SIGNAL INPUT RELATED PROBLEMS:

• 

The input signal value obtained from the connected sensor exceeds the lower or upper boundary limits possible for the input 

 

circuit. There are a variety of potential causes itemized below:

 

o

Confirm the type of sensor is being connected matches the mating transmitter. There are a wide variety of TT-MA transmitters 

that interface with broad range of sensor types. For example:

 

ƒ

The TT-MA pH and ISE transmitters come in separate versions that are for use with sensors without integral preamplifiers 

(TT-MA-pH and TT-MA-ISE) or else that will only work with pH and ISE sensors that have integral preamplifiers (TT-MA-

pH-X and TT-MA-ISE-X).

 

ƒ

The conductivity sensor employed must be connected to a TT-MA-CON transmitter for use with that given cell constant. 

Confirm by checking labels on your conductivity sensor and the TT-MA-CON conductivity transmitter to ensure that the 

cell constants match.

 

ƒ

The  TT-MA-DO  transmitters  can  only  be  used  with  the  standard  thickness  membrane  sensors  such  as  the  ASTDO

 

whereas the TT-MA-DO-T transmitters can only be used with the thick style membrane sensor such as the AST-DO-T models.

 

o

Leads are not secure or the colour coding is not correct. Please refer to the documentation supplied in hard copy with your 

shipment or the TT-MA website for assistance with obtaining proper wiring schematic. If you are not sure please contact Turtle 

Tough factory for assistance.

 

o

The connected sensor is either damaged or expired. Connect a different known working sensor on the same transmitter as a 

troubleshooting step to determine if the issue is with the input board in question or whether it is owing to the connected sensor.

If you have gone through all of the troubleshooting steps detailed above and are still receiving the “OFL” or “UFL” error then most 

likely your input board has stopped working properly. Contact the factory to obtain a valid RMA so that the transmitter in question 

can be returned for evaluation and warranty repaired/replaced as may be applicable. You will need the 11 digit serial number that 

can be found in the small label below the faceplate when making an RMA request.

How can I determine the production date and dispatch date of the TT-MA transmitter?

The production date formatted as (yy.m) is displayed by pressing the “

Down

” & “

Mode

” key simultaneously in main TT-MA measure

-

ment mode. The month shows as 1..9 and A for October, B for November and C for December. For example October 2014 will display 

as “14.A”. The dispatch date from Turtle Tough can be determined from the small label showing the 11 digit numeric serial number 

located below the faceplate. This serial number label should not be removed or adulterated in any way or else the warranty might be 

voided.

Special note about production & dispatch dates:

The production and dispatch dates are altogether decoupled. The two-year warranty period shall begin from the dispatch date and not the 

production date. You may be asked to report the both the production date and serial number of the transmitter as part of the technical support 

process.
