Register Description
KL3201, KL3202 and KL3204 13
Terminal-specific register description
Process variables R0: Raw ADC value X_R
This register contains the raw ADC value.
R1: Raw ADC value of the line resistance between +R1 - RL1 or +R2 -
RL2
R2 to R5: Reserved
R6: Diagnostic register
High byte: not used
Low byte: status byte
Manufacturer parameters R17: Hardware compensation - offset (B_a)
16 bit signed integer
This register is used for offset compensation of the terminal (Eq. 1.1).
Register value approx. 0xEDXX
R18: Hardware compensation - gain (A_a)
16 bits * 16
-5 (approx. 0.01907 Ω/digit)
This register is used for gain compensation of the terminal (Eq. 1.1).
Register value approx. 0x27XX
R19: Manufacturer scaling - offset (B_h)
16 bit signed integer [0x0000]
This register contains the offset of the manufacturer's straight-line equation
(1.5). The straight-line equation is activated via register R32.
R20: Manufacturer scaling - gain (A_h)
16 bits signed integer *2
-8 [0x00A0]
This register contains the scaling factor of the manufacturer's straight-line
equation (1.5). The straight-line equation is activated via register R32.
R21: Additional offset register for two-wire connection
The value of register 1 at short circuit +R1-RL1 or +R2-RL2
[approx. 0x01AX]
