Output parameters - HMM170

Table 1. Availability of output parameters

Output parameter is available

Output parameter is unavailable unless real temperature is written to Modbus register 0334_hex from an external source

Output parameter is locked (value stays at latest valid reading) until measurement is possible again

Output parameter is not valid for sensor type
