* Using internal transmitter power supply
** Use 100Ω shunt resistor provided with instrument
*** Only available if option board fitted
**** 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
