OM-EL-1 measures, displays, records and controls temperature, humidity, pH, voltage, current, etc., with a memory for 8064 readings and a battery life of up
to 3 years**. OM-EL-1 can operate as a 'stand alone' logger or be permanently connected to a system. The OM-EL-1 serial link is addressable and up to 8
loggers can be connected to one serial port. The PC software operates under Windows 3.1 and does not require specialist skill to operate. Data output is in
text format and can be easily integrated into any popular spreadsheet. Graphical output is possible under OM-EL-WIN. Consult the EasyLog software
manual for further details.

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 or leads. Take care to connect correctly.

TEMPERATURE (with thermocouple)
A 'K' type thermocouple can be connected
directly to the OM-EL-1. The range should
be selected in the OM-EL-WIN software.
VOLTAGE*
D.C. voltage within the ranges of 0-2V or
0-20V can be connected directly to the
OM-EL-1. Ensure the appropriate range
has been selected in advance within the
OM-EL-WIN software. For higher voltage
measurement an external potential
divider network should be added.
TEMPERATURE (internal)
No sensor needed. The OM-EL-1
uses its internal temperature
A
sensor.
Ensure A to B is
B
SHORTED.
pH (with internal reference)
Connect a pH probe that has an internal
reference cell directly to the OM-EL-1.
(refer to the probe's instruction manual).
NOTES

SENTEK P14 probe is used.

CURRENT*
D.C. current can be measured up to 2A
maximum by using an external 1Ω 6watt
shunt across the input. Select the voltage
'0-2V range' in OM-EL-WIN software and
'A' in the display symbols.
HUMIDITY
A capacitive humidity sensor can be
connected directly to the EasyLog.

RATE COUNT*
OM-EL-1 counts the number of pulses on
the input during the sample interval (e.g.:
every 5s, 10s, 20s etc.). At the end of each
sample interval, the count number is stored
and the counter is reset to zero. A pulsed
input of 0-5V can be directly connected to
the OM-EL-1. The counter is incremented
on the falling edge.
*NOTES
1. When using the serial link, ensure that all signals are isolated from the computer ground.
2. When using several loggers together, ensure all signals are isolated or use the same ground.
