4.1.5 Digital Channel Parameters
(CHID, INC, TDAY, TOT, TYPED, UD)
The “Channel ID” (
CHID
) is a 7 digit user definable number that should be set to uniquely
set to identify the channel.
CHID<CR>
Displays the present Digital Channel ID
CHID=0012345<CR>
Sets the Digital Channel ID to 0012345
The “Increment” (
INC
) is a parameter that specifies the quantity that each contact closure
represents. This might be 0.2mm of rain for a tipping bucket rain gauge, or 10 litres of water
for a flow meter, or 1 widget for a product counter. The parameter is split into 2 parts – the
first part is the amount that each contact closure represents, and the second part is the number
of contact closures that represent one event. The increment command has 5 different
acceptable formats.
INC<CR>
Display the existing increment parameter.
INC=0.01/01<CR>
Defines say a TBRG bucket of 0.01 inches of water, and one tip
represents one logged event.
INC=0.2/01<CR>
Defines say a TBRG bucket of 0.2 mm of water, and one tip
represents one logged event.
INC=10/10<CR>
Defines say 10 litres of water per contact closure of a flow
meter, and 10 such closures logged as one event. This means
that each event represents100 litres of water.
INC=100/01<CR>
Defines say 100 litres of water per contact closure of a flow
meter, and 1 such closure logged as one event.
INC=1000/05<CR>
Defines say 1000 washers in a box, and 5 such boxes logged as
one event. This means that each event represents 5000 washers.
The “Total” (
TOT
) command allows the Total number, of whatever is being counted, to be
displayed. This is the total since the last reset – or the total since the last CLR record clear.
TOT<CR>
Displays the total of what is being counted since the last record
clear.
The “Total Today” (
TDAY
) command allows the Total number, of whatever is being
counted, to be displayed. This is the total today since midnight.
TDAY<CR>
Displays the total of what is being counted since midnight.
