INSTRUCTION

SHEET

M-3141

OM-EL-1-12BIT isan easy to usedisplay modulecapable of measuring, recording,displaying and controllingtemperature (Pt100), voltage andcurrent. With
12 bit A/D resolution, a memory for 8000 readings and a battery life of up to 3 years, OM-EL-1-12BIT can operate as a 'stand alone' logger or bepermanently
connected to a system. The OM-EL-1-12BIT serial link is addressableand upto 8loggers canbe connected to one serial port. The PC software operatesunder
Windowsand doesnot require specialist skill tooperate. Data output is intext formatand can be easily integratedinto mostpopular spreadsheets. Graphical
output is possibleunder OM-EL-WIN. Consult theEasyLog softwaremanual forfurther details.

NOTE -

It is possible to measure parameters other than those outlined below. Use an appropriate sensor and conditioning circuit to

convert the parameterto bemeasured into alinear voltageor current andapply thissignal to asuitably scaledOM-EL-1-12BITmodule.

Measurement signals must always be isolated from the communications signals.
