SECTION 3
Pr.11.3 Test mA (D = 4mA)
This parameter outputs a mA value selected by the user. A value of 4, 8, 12 , 16 or
20mA can be outputted and measured at terminals 12 & 13, to test the external
circuitry.

Description
11.3.1 Analogue set output 4mA Sets the analogue output to 4mA
11.3.2 Analogue set output 8mA Sets the analogue output to 8mA
11.3.3 Analogue set output 12mA Sets the analogue output to 12mA
11.3.4 Analogue set output 16mA Sets the analogue output to 16mA
11.3.5 Analogue set output 20mA Sets the analogue output to 20mA
11.3.6 End analogue test Exits analogue test
Pr.11.4
Analogue Scale
11.4.1 Analogue Datum (D = 0.00)
If an analogue output is required with a zero different from the measurement zero
(Pr.2.0) then an offset defined as a percentage of the measurement span/flow/volume
etc., can be entered here.
11.4.2 Analogue Span (D = 100.0)
If an analogue output is required with a span different to that defined for the
measurement (Pr.3.0) then an alternative value defined as a percentage of the
measurement span/flow/volume etc., can be entered here. A value of zero is ignored.
Miscellaneous
Pr.12.1
Offset (D = 0.00)
Both negative and positive values can be input. This value must be entered in metres.
This parameter has two uses:
1. It can be used to correct minor reading errors on the display
2. It can be used to prevent loss-of-echo when the target can go further
away from the transducer than the desired span.
e.g. a) When a channel floor is lower than the zero point of a "V" notch weir.
b) To set an elevated zero level in a vessel, which is not normally completely
emptied.
Add the extra depth to Pr.2.0 and enter minus
the extra depth at Pr.12.1 in metres.
Pr.12.2
Passcode Security Code Store
A new security code can be entered at this parameter, but after entry it is scrambled.
Refer to Hycontrol if you forget your security code and quote the number displayed
here.
