The transmitter output signal, however, may be any voltage between 0 to 5 VDC (For e.g. 0 to 1 VDC,1 to 3.6 VDC, 0 to 3.3 VDC etc.). The value for `Range Low' and `Range High' parameters must be corresponding to 0 and 5 VDC only. For this, use the following formulae for computing the `Range Low' and `Range High' values. 100 Range Low = Span X (0 - Signal Low) 100.0 Range High = Span X (5 - Signal Low) (where; Span = Signal High - Signal Low) Example 1 Signal Low = 0 VDC, signal High = 1.0 Vdc Range Low = 100.0 1.0 X (0 - 0) = 0.0 Range High = 100.0 X (5 - 0) = 500.0 1.0 Example 2 Signal Low = 0 VDC, signal High = 3.3 VDC Here, Span = 3.3 -0 = 3.3 VDC Example 3 Signal Low = 1.0 VDC, signal High = 3.6 VDC Here, Span = 3.6 - 1.0 = 2.6 VDC Range Low = 100.0 2.6 X (0 - 1.0) = -38.5 Range High = 100.0 2.6 X (5 - 1.0) = 153.8 Range Low = 100.0 3.3 X (0 - 0) = 0.0 Range High = 100.0 3.3 X (5 - 0) = 151.5 FRONT PANEL LAYOUT Front Panel PPI HumiTherm-c °C Upper Readout Lower Readout Tune Indicator Alarm -1 Indicator PAGE Key %RH 1 2 AL1 TUN AL2 Output-1 Indicator Output-2 Indicator Alarm-2 Indicator ENTER Key DOWN Key UP Key Symbol Key PAGE Keys Operation Function Press to enter or exit set-up mode.

PV Error Indications For Dry Bulb Temperature (Upper Readout) Message PV Error Type Over-range (Dry-Bulb Temp. above Max. Range) Under-range (Dry-Bulb Temp. below Min. Range) Open (Sensor open / broken) PV Error Indications For Relative Humidity (RH) (Lower Readout) Message PV Error Type Over-range (Wet-Bulb Temp. above Max. Range) Under-range (Wet-Bulb Temp. below Min. Range) Open (Sensor open / broken) Either Dry Bulb Temp. is below 20.0°C or above 162.0°C. The error may also occur if Wet Bulb depression is more then 60.0°C. INPUT 1 OUTPUT 1 & 2 Pt100 + SERIAL COMMS.
