Setpoint
By default the mA Output will represent the empty (0 or 4mA dependant
on (P830) mA Range) and 100% of the operational span (20mA), but you
may wish to have the output represent a section of the operational span. For
example, the application has an operational span of 20 feet but output is to
represent empty (0 or 4mA dependant on (P830) mA Range) to a level of
15 feet (20mA). If so P834 (Low Level) should be set to 0.00 feet and P835
(High Level) should be set to 15 feet.
P834 mA Low Value
This parameter sets, in Measurement Units (P104), the value of ‘level’,
‘distance’, ‘space’, ‘average level’ or ‘differential level’, depending on the
selected mA Out Mode (P831), at which the low mA output will occur (0
or 4mA dependant on (P830) mA Range)
Default = 0.000 feet
P835 mA High Value
This parameter sets, in Measurement Units (P104), the value of ‘level’,
‘distance’, ‘space’, ‘average level’ or ‘differential level’, depending on the
selected mA Out Mode (P831) at which the high mA output will occur
(20mA). Default = 19.685 feet
Limits
P836 mA Low Limit
This parameter sets the lowest value that the mA output will drop to, the
default is 0mA, but you can override this if the device you connect to cannot
for example accept less than 2mA, yet you want to use the 0-20mA range.
Default = 0.00mA
P837 mA High Limit
This parameter sets the highest value that the mA output will rise to, the
default is 20 mA, but you can override this if the device you connect to
cannot for example accept more than 18 mA, yet you want to use the 0-20
mA range. Default = 20.00mA
Trim
P838 mA Low Trim
If the remote device you are connected to is not calibrated, and not showing
the correct low value (reading), then you can trim it using this parameter.
You can either type in the offset directly, or use the arrow keys to move the
output up and down until you get the expected result (reading) on the remote
device that the mA output is connected to.
