3.3.6.3 Unit Parameters
Common parameters
• Unit of measurement: it is possible to configure the temperature reading °Celsius or °Fahrenheit
0 = °Celsius
1 = °Fahrenheit
• Noise suppression: suppresses electrical noise generated by mains electricity supply. This parameter works in conjunction with the
"Acquisition Filter" parameter.
0 = 50 Hz: suppresses noise generated by 50Hz mains electricity supply
1 = 60 Hz: suppresses noise generated by 60Hz mains electricity supply
2 = 50/60 Hz slow: suppresses noise generated by 50Hz and 60Hz mains electricity supply. A high level of filtering is achieved, but with a
delay in data acquisition.
3 = 50/60 Hz fast: uppresses noise generated by 50Hz and 60Hz mains electricity supply. Very fast acquisition is achieved, but with a low
level of filtering.

• Type of sensor and related thermal coefficient: possible choice of the type of sensor used among those available.
• Type of connection (for RTD only): possible choice of the type of sensor connection, if with 2, 3 or 4 wires.
0 = 2 wires
1 = 3 wires
2 = 4 wires
• Cold joint compensation (for TC only): possible choice of an external cold joint instead of the one already installed internally.
The external cold joint (Pt1000) is recommended in case of sudden changes in the ambient temperature.
0 = External
1 = Internal
• Measurement resolution: possible choice of measurement resolution in tenths or hundredths of °C.
The resolution in hundredths only applies to RTD sensors, with temperature reading of maximum +/- 327°C.
0 = 0.1
1 = 0.01
• Acquisition filter: it defines the type of digital filter. It works in conjunction with the "Noise suppression" parameter.
By setting the Sync 4 filter, a level of filtering higher than the one with the Sync 3 filter is achieved, but with a longer delay in data acquisition.
0 = Sync3
1 = Sync4
• Sensor disconnected signalling: if enabled, the breakage of a wire generates an alarm.
0 = Disabled
1 = Enabled
• Short-circuit signalling (for RTD only): if enabled, a short circuit of the sensor connection generates an alarm.
0 = Disabled
1 = Enabled
• Minimum value monitor / Maximum value monitor: when these two functions are enabled, an alarm is generated when the temperature goes
below the set Minimum value or above the set Maximum value.
Minimum value monitor: 0 = Disabled Maximum value monitor: 0 = Disabled
1 = Enabled 1 = Enabled
• Measured Value Filter: a mathematical filter that ensures a more stable temperature reading. By setting a filter value on the sampling of the
highest signal, improved reading stability is achieved but with a longer delay in data display.
0 = No sensor connected 7 = Pt 500 (TK=0.00391) 14 = TC Type J
1 = Pt 100 (TK=0.00385) 8 = Pt 1000 (TK=0.00391) 15 = TC Type T
2 = Pt 200 (TK=0.00385) 9 = Ni 100 (TK=0.00617) 16 = TC Type K
3 = Pt 500 (TK=0.00385) 10 = Ni 200 (TK=0.00617) 17 = TC Type N
4 = Pt 1000 (TK=0.00385) 11 = Ni 500 (TK=0.00617) 18 = TC Type S
5 = Pt 100 (TK=0.00391) 12 = Ni 1000 (TK=0.00617) 19 = TC Type B
6 = Pt 200 (TK=0.00391) 13 = TC Type E 20 = TC Type R
