Address Definition
0x15C
For the standard PK2100, this is current in units of 1.0 µA
corresponding to voltage output of 2.000V when set for 0-
20 mA output into nominal 392-Ω load resistor. Typically,
near 4000. For the 12-volt PK2100, the output range is 0-
15 mA.
0x15E For the standard PK2100, this is current in units of 1.0 µA
corresponding to voltage output of 10.000 V when is set
for 0-20 mA output into nominal 392-Ω load resistor. For
the 12-volt PK2100, the output range is 0-15 mA.
0x160 With shorting jumper H7 connected, these are 16-bit
numbers a
0
and a
1
high-gain plus-side inputs in the gain
formula
y = a
1
× (x
1
+ a
0
)
with the minus side grounded. If the minus side is not
grounded, the formula is
y = a
1
× ( x
1
+ a
0
) – b
1
× x
2
.
where b
1
is the minus-side gain and can be computed from
the calibration constants stored at location 0x164. The
value y is the output of the high-gain amplifier read with
universal input channel 7. The value x
1
is the plus-side
input read with universal input channel 8 and x
2
is the
minus-side input.
The coefficient a
0
is signed and is in units of 0.01 mV.
The coefficient a
1
is the unsigned dimensionless gain
expressed in units such that a gain of 10 is equal to 2000.
0x164
With shorting jumper H7 removed, these are 16-bit
numbers a
0
and a
1
high gain plus-side input in the gain
formula
y = a
1
× (x
1
+ a
0
)
with the minus side grounded. If the minus side is not
grounded, the formula becomes
y = a
1
× ( x
1
+ a
0
) – b
1
× x
2
.
where b
1
is the minus-side gain and can be computed as
a
1
– 1.
The library function up_higain() supports the default
case (H7 unjumpered).
0x168 Reserved
0x16A
Resistance of excitation resistor for high gain plus input in
units of Ω. Nominal value 10 kΩ. An unsigned integer.
