EL-1-12BIT
WINDOWS Compatible Data Logger
EL-1-12BIT is an easy to use display module capable of measuring, recording, displaying and controlling temperature (Pt 100), voltage and current. With
12 bit A/D resolution, a memory for 8000 readings and a battery life of up to 3 years, EL-1-12BIT can operate as a 'stand alone' logger or be permanently
connected to a system. The EL-1-12BIT serial link is addressable and up to 8 loggers can be connected to one serial port. The PC software operates under
Windows and does not require specialist skill to operate. Data output is in text format and can be easily integrated into most popular spreadsheets.
Graphical output is possible under EL-WIN. Consult the EasyLog software manual for further details.

IMPORTANT NOTE-
Always remove the Lithium battery from the module BEFORE connecting an external power supply to the module.
Failure to do so may cause the battery to explode.
BATTERY REPLACEMENT
Only use ½AA 3.6V lithium. The list below is not exhaustive. Check with supplier that the battery you are ordering is 'press fit' and is not fitted with
solder tags. Take care to connect correctly. DO NOT PRESS ON LCD WHEN INSERTING BATTERY.

WARNING: Handle lithium batteries carefully - observe warnings on battery casing. Dispose of in accordance with local regulations.
APPLICATIONS
NOTE -It is possible to measure parameters other than those outlined below. Use an appropriate sensor and conditioning circuit to
convert the parameter to be measured into a linear voltage or current and apply this signal to a suitably scaled EL-1-12BIT module.
Measurement signals must always be isolated from the communications signals.
