The AN1
and
AN2
Pages (MetPak Pro Base Station) can be used to select:-
AN1 or 2 Sensor
ON
or OFF
Sensor Type – Choose a title from drop down list.
Units – Allows a choice of measurement units depending on sensor chosen.
Analogue Input Type – Select Voltage or Current.
Substitute Name field available for typing in a substitute name between 3 to 8 characters long.
Low – Match to low scale of external sensor (±9998.0000 possible).
High – Match to high scale of external sensor (±9998.0000 possible).
MetSet AN1 and AN2 Edit pages can be used to set a MetPak Pro Base Station low value and
high value range figure to be input to match the output range of the connected sensor.
For instance if a 0-5v Pressure Sensor scaled over a range of 600 to 1100 Milli-bars is connected
to AN1, then set MetSet AN1 Edit Screen for low value 600 and high value to 1100 and save this
as device setting.
The MetPak Pro Base Station will then output the actual pressure reading value e.g. 1027.1 in the
AN1 position of the digital data string.
Similarly if a 0-5v Temperature probe were used on AN2 scaled over a range –50 to +70 degrees,
then set AN2 low value to –50 and high value to 70.
NOTE:
In the event that the input voltage exceeds 5.05v dc an overflow character E will appear in the
digital data string.
In the event that the input current is less than 3.96mA an error character X will appear in the digital
data string.
In the event that the input current is more than 20.2mA an overflow character E will appear in the
digital data string.
