Instrument has small signal removal function only when it with evolution function.
3.4.12 Methods to return to measure state:
•Manual return: Under parameter setting mode, pressing SET key for 5 seconds the instrument will automatically return to measured value display state.
•Automatic return: Under parameter setting mode, does not press any key for 30 seconds, the instrument will automatically return to measured value display state.

Modification of transmission output signal

Short-circuit ring which is designed on the transmission output board may chang the output of current or voltage according to method of table 6. User parameters may be set by method of table 7, Pb3 and KK3 may change the upper/lower range of output signal.

| DC current output| DC voltage output
---|---|---
Short-circuiting ring state| |
Signal output end voltage, resistance| voltage: 20—30V resistance: infinite| voltage: 0-,-.10V
resistance: 250-5000 or infinite

Signals Pb13, Pb23, Kk13, Kk23 output different ranges may be set according to the following table: Table 7

| 0 ∼ 10mA| 4∼ 20mA
l -6V| 0∼ 20mA
0–#5V/0–#10V
---|---|---|---
Pb13, Pb23| 0.0| 20.0| 0.0
KK13, KK23| 0.500| 1.000| 1.000

Calibration of display transmit measure

6.1 Calibration of display range: When error exists between H/L limit display range and actual range, range can be adjusted by modifing Pbl and KK1, the details are as the following method:
ICIC1= scheduled range ÷ display range X initial Kk 1 (scheduled range: SLH- SLL)
Pbl= lower limit of scheduled range—lower limit of display range X KU +initial Pbl

For example: a DC current 4-20mA input instrument, measuring rang is
200-1000Kpa, while calibration, find that when input 4mA, displays
-202, when input 4mA, displays 1008. (Initial Pb171, initial KK1=1)

According to the formula:
KK1=scheduled range ÷ display range X initial KK1
= [1000- (-200)] ÷ [1008+202)] X 1
= 1200+1210 X 1 0.992

Pbl= lower limit of scheduled range-lower limit of display range X KK1+ initial Pbl= -200- (-202 X 0.992) +0=0.384≈0.4
Set: Pb17,1.4, KK1 .992

6.2 Calibration of transmission range: When error exist between H/L limit transmission output and actual range, range can be adjusted by modifying Pb3 and
KK3, the details are as the following method:
KK3= scheduled output range ÷ actual output range X initial KK3 (Scheduled output range: OUH-OUL)
Pb3 = scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3

For example A DC current signal 4″-20mA input instrument, measuring range is -200-1000Kpa, transmission output is 4-20mA; While calibration, find that the instrument display is very accurate; when input 4mA and 20mA, the instrument output 3.9mA and 20.1mA respectively, set initial instrument Pb3=20.0, KK3=1.000.

According to the formula:
KK3=scheduled output range ÷ actual output range X initial Kk3
= (20-4) ÷ (20.1-3.9) X 1.000
= 164-16.2 X 14.988
Pb3= scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3
= 4-3.9 X 0.988 +20.0 =20.1
Set: Pb3=20.1, Kk3=0.988

Note : Before calibrating transmission output, first ensure that the display is correct or not, Pbl, Pb3 modified value precise to one digit behind decimal point.
