Please check in advance which HydroTracer model you are using. This can be determined by the model name and/or the serial number. There are 3 model series:

• HydroTracer HT3
• HydroTracer FLV HT2
• HydroTracer FMX or FLV

 
Each model series has its own serial number (SN) coding.

• HT 3xxx XY identifies the HydroTracer HT3
• HT 2xxx XY stands for the HydroTracer FLV HT2
• Serial numbers starting with “F …” identify the model series HydroTracer FMX or FLV
