Example 1:

Example 2 (Negative Slope):
mA when the tank is empty. The PAXLCL is to readout 90.0 tons at full tank
and zero when empty.
ADJUSTMENTS
6.0 A
A PAXLCL is to be calibrated to match a flow transducer whose output is 10
READOUT SPAN (Rs) = 1375 0 = 1375
SWING CURRENT (Is) = 50 mA 10 mA = 40 mA
A level measuring device puts out 6 mA when a storage tank is full and 15
READOUT SPAN (Rs) = 900 0 = 900
SWING CURRENT (Is) = 6 mA (@ max rdg) - 15 mA (@ min rdg) = -9 mA
In this case, the signal current is reverse [Term 3 (-) with respect to Term 5
(+)] causing the readout to go “down” (increasingly negative) as the negative
current increases.

to get a readout of 1375 @ 40 mA per
Steps 5 and 6. Note: With the full
standard swing of 40 mA, the coarse
span switch reference markings can be
used to determine settings as follows:
when the 10 mA min. current is first applied can be used to determine the
offset switch settings.) In this example the readout will be (+) 344 when the
10 mA min. current is first applied. Applying -344 offset then reduces the
readout to zero @ 10 mA.

READOUT SPAN (Rs) = +1500 (1500) = 3000

a readout of +1500 @ 8 mA.
Apply (-) offset per Step 7 to get a
reading of -1500 @ 4 mA.
Check min. and max. extremes and
tweak if required to get desired
readout @ 4 and 20 mA per Step 8.

Set transfer curve slope with span
full READOUT SPAN of 3000 cannot be obtained during zero based span
adjustment. However, dividing both the READOUT SPAN and SWING
CURRENT by two, i.e. 1500 readout @ 8 mA, allows the span adjustment
to be made for the proper transfer curve slope.
