TESTO 312 - Pressure Transducer (Accessories)

Normal use
The pressure transducer protects the testo 312
measuring instrument from moisture and high
temperatures: measures vapour and water pressure.
Measuring
Do not use an extension cable between the pressure
transducer and the instrument.
1 Connect connection A of the pressure transducer
directly to the instrument (+).
2 Switch on instrument.
3 Press “Start” and wait for calibration phase (5s).
4 Connect connection P of the pressure transducer
directly to the control pressure pipe.
Observe maximum pressure range of instrument and the
