* Using internal transmitter power supply
** Use 100Ω shunt resistor provided with instrument
*** For correct broken sensor operation with voltage inputs, fit a 100KΩ pull-up resistor
# Fit the CJ sensor supplied if I/P1 or I/P2 are THC inputs
## I/P2 can only be used with THC inputs if I/P1 is also used as a THC input
### Fit the CJ sensor supplied if I/P3 is a THC input
Note. The battery is a 3 Volt non-replaceable lithium cell.
