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.

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

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
