Instructions for Use:
This instrument is used for indicating temperature and pressure with 4~20mA and other DC signal inputs, and has a transmitter output function.
The terminal block arrangement of the instrument is shown in Figures 1.7 and 1.8. Figure 1.7 shows the F96 and F144 models, and Figure 1.8 shows the F72 model.
There are two potentiometer adjustment knobs on the back of the instrument. The left one is for upper limit full-scale adjustment, and the right one is for lower limit zero-point adjustment. The instrument is set at the factory according to the order requirements; however, users can adjust it themselves if needed on-site.
For special purpose instruments, please add "J" after the first half of the model number (only applicable to 240° instruments). For example, F96JM-DC
