Panel Meter LAP-35
Panel meter 96x48mm for mA current loop signals
loop powered from the signal loop
Panel meter for mAcurrent loop signals. Instrument self pow-
ered from the mA signal loop. LCD display. Reading scalable
to engineering units.
Standard 96x48mm size, with 12.7mm digit height, and
resolution from 1999 to -199, with decimal point selection.
Connections via plug-in screw terminals and conguration
via internal jumpers for range selection and span and offset
potentiometers at the rear of the instrument. For application
on industrial environments.

Slope reading selection
Direct S2-D, S2-E, S3-E, S3-F
Inverse S2-C, S2-F
Select the jumpers for the desired reading slope.
As standard, the direct slope is used (reading increases
when signal increases). The inverse slope congures the
reading to decrease when reading increases.
Span and offset range selection
Low range S3-A, S3-G Span from 385 to 785
Offset from -160 to 100
Middle range S3-B, S3-G Span from 750 to 1500
Offset from -260 to 200
High range S3-G Span from 1090 to 1999
Offset from -380 to 560
Select the jumpers for the desired span and offset range.

Readjustment procedure
1- Take all jumpers out
2- Select appropriate signal range jumpers
3- Select appropriate slope reading jumpers
4-Select appropriate spanandoffsetjumpers.Calculate span
and offset values according to the example below. Example
given for an adjustment of 4/20mA = 0/1000
IL (input signal low) = 4mA RL (reading low)=0
IH (input signal high)= 20mA RH (reading high)=1000
G = ( RH - RL ) / ( IH - IL )
Offset = RL - ( IL x G )
Span = RH
If value obtained for G is higher than 125 or values for span
and offset do not t into any of the three available ranges,
then the adjustment is out of the capabilities of the instrument.
5- Select appropriate decimal point jumpers
6- Connect a signal generator to the input terminals
7- Generate the input signal low (4mA)
Operate Offset potentiometer until the value for reading
low is reached (0)
8- Generate the input signal high (20mA)
Operate Span potentiometer, until the value for reading
high is reached (1000)
9- Repeat steps 7 and 8, until desired accuracy is obtained
