2) The 4-20mA range settings are reset to full span whenever the moisture units are
altered.
Operation – In the ‘Setup Menu’ move the cursor bar to highlight the ‘Select Units’
option and press the ‘ ’ key. The ‘Primary Units’ sub-menu is displayed. Run through
the options until the required engineering unit is highlighted; confirm the selection by
pressing the ‘ ’ key. The SADPminiEx automatically reverts to the ‘Exit’ option in the
‘Setup Menu’.
Note: The PPB Moisture Engineering Units has an upper display limit of 10000 PPB, Change
units to PPM above this moisture level.
11.1.2
Pressure Calc
Description – This sub-menu has five options allowing the user to select any one of four
Pressure Engineering Units and to exit the menu. This function then allows the
SADPminiEx to display Dewpoint ºC and ºF at @ pressure. When this function is
selected, the main display screen will display the pressure at which the Dewpoint
reading is calculated.
Operation – In the ‘Setup Menu’ select the ‘Pressure Calc’ option. In the ‘Pressure
Units’ sub-menu run through the options until the required engineering unit is
highlighted; confirm the selection by pressing the ‘ ’ key. The SADPminiEx then
requires that a numerical pressure value be entered in the selected units. The display
format relates to the pressure units chosen. Once a pressure value is entered, the
SADPminiEx automatically reverts to the ‘Exit’ option in the ‘Setup Menu’.
Note: See ‘SADPminiEx Specification’ for detailed information on Pressure Engineering Units.
Warning: This function is purely an internal calculation and DOES NOT
allow an elevated pressure to be applied to the measuring head.
11.1.3
4-20mA Output (4-20mA and Full Logging versions only)
FOR USE IN SAFE AREA ONLY
Description – The 4-20 option allows the user to set the range over which the 4-20mA
output will span. The default setting is for the output range to cover the full operating
range of the sensor type fitted in the SADPminiEx e.g. for a ‘B’ type sensor 4mA equals
–80°C and 20mA equals 20°C. However, it is possible to set a more focused range,
such as 4mA equals -60°C and 20mA equals –20°C.
Operation – In the ‘Setup Menu’ select the ‘4-20mA Output’ option. The SADPminiEx
requires that a value be entered for the 4mA lower limit. The current value is displayed,
in the active moisture-engineering units. Once the new value is entered, the
SADPminiEx requires that another value be entered for the 20mA upper limit. Once
