1.1 Features of the logger
Congratulations on purchasing the iLog series of data loggers! These portable battery powered
data loggers allow recording information and saving measurements to a 4MB flash memory for
later retrieval.
The internal lithium battery provides up to 12 years of instantaneous logging operation when
sampling at interval of one minute.
An iLog data logger can be manipulated by SiteView Windows software for data downloading,
logging management, and property configuration. It has both TTL-compatible serial port and
USB interface for different communications requirements.
An iLog data logger features a wide sampling interval range from 20 milliseconds to 12 hours,
providing alternative to data acquisition devices and paper chart recorders.
An iLog data logger provides alarm outputs controlled by the low and high programmable
alarm thresholds of each enabled channel. The alarm control outputs can be used to turn on/off
external alarm devices such as strobe lights, sirens or alarm telephone diallers.
An iLog data logger also has an excitation control output used to switch the power supply of the
external transducer/transmitter.
An iLog data logger contains one internal thermistor channel, and one external process signal
channels. The 16-bit analog-to-digital converter makes the measurements more precise and
accurate.
And iLog data logger also has a rugged, splash resistant aluminum enclosure.
1.2 Approvals
All iLog Series data loggers are in conformity with the EN standard(s) listed below:
EN 61000-6-2:[2005]
General standards –Immunity for industrial environments
EN 61000-6-3:[2007]

iLog Data Loggers User’s Manual Page 7/63
General standards –Emission standard for residential, commercial and light-
industrial environments
following the provisions of the following directive(s)
2004/108/EC Electromagnetic compatibility (EMC)
All iLog Series of data loggers comply with Part15 of the FCC Rules. Operation is subject to
the following two conditions:
1. These devices may not cause harmful interference, and
2. These devices must accept any interference received, including interference that may cause
undesired operation.
1.3 Care of the logger
Although the iLog data loggers are weather resistant, the loggers are designed to work in-door
and in humid atmospheres of up to 95% RH non-condensing. They should be protected against
immersion. The environment temperature should be within –40 to +70°C (-40 to + 158°F).
1.4 Identity of the logger
Each logger has its own unique serial number, which can be found on the back of the enclosure.
The serial number is used to identify the logger and enable us to keep a record of its history like
calibrations and warranty. Please reference it in any correspondence with MEI.
1.5 Battery
The battery lasts in excess of 12 years when sampling at 1-minute intervals. When the battery is
nearing the end of its service life, the on-board status LED will glow in amber each time the
logger is sampling the data. The battery indicator on the status window in SiteView software
will also display warning of low battery level. The battery operates approximately one or two
weeks from the time the logger first indicates a low battery, but we recommend that the battery
be changed as soon as the warning is displayed. The battery is factory replaceable only.
1.6 Recalibration
Any iLog data logger is supplied with all channels pre-calibrated and should not require any
further recalibration for a period of 12 months.

iLog Data Loggers User’s Manual Page 8/63
We recommend the logger be recalibrated every year. You may recalibrate the logger longer
than a year depending on your application standard.
You may return the logger to the supplier for recalibration service or recalibrate it on your own
via SiteView software.
SiteView software provides two-point calibration for the most of the loggers.
1.7 Safety Warning
Maximum Input Voltage Range
For logger model: iVDC-10, iTC-80:
The logger is designed to measure single common ground DC voltages in the range up to 10
VDC. Any voltages over this range may cause permanent damage to the device.
For logger model: iBG-[X]:
The logger is designed to measure strain gauge/bridge signal up to ±520mVDC. Any
voltages over this range may cause permanent damage to the device.
Maximum Input Current Range
For logger model: iCDC-25:
The logger is designed to measure single common ground DC current in the range up to 25
mA. Any current over this range may cause permanent damage to the device.
External Power Supply
When using external power supply (via USB, Serial Port, Device Server, or thirty party +5
VDC power supply) to power the logger please make sure that the external power supply has
the same common ground with the external input process signals.
When using other third party external power supplies, please make sure the voltage of the
external power supply is +5 VDC (+/- 5% ripple).
Grounding
The common ground of the iLog data logger is connected directly to the ground of the input
process signals and the ground of the external power supply (if applicable).

Then you need to change temperature coefficient values by clicking “Change Coefficients”
button in “Action” column:
In the pop-up dialog enter new temperature coefficient values and click “OK” button.

iLog Data Loggers User’s Manual Page 16/63
You can also use a custom equation to do the same job or even more complicated
calculation. An example of external thermistor equation is included in SiteView package.
When you create your own equation you can refer to this equation and replace those
temperature coefficients with the ones obtained from the thermistor manufacturer. The
contents of the sample equation looks like this:

iLog Data Loggers User’s Manual Page 17/63
Once you have created your equation, you can apply it to the channel:

What is a Strain Gauge
A strain gauge (also strain gage) is a device used to measure the strain of an object.
The gauge is attached to the object by a suitable adhesive. As the object is deformed, the foil is
deformed, causing its electrical resistance to change. This resistance change, usually measured
using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.
The gauge factor GF is defined as:
where
is the change in resistance caused by strain,
is the resistance of the undeformed gauge, and
is strain.
A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by
balancing two legs of a bridge circuit. The Wheatstone bridge consists of four resistances (R1,
R2, R3 and R4), an excitation voltage and an output voltage. Generally, one or more of the
resistances are variable and change in accordance with some physical phenomenon, such as
strain in this case. The Wheatstone bridge then converts this change in resistance to a change in
voltage.
There are 3 configurations are used - quarter bridge, half bridge or full bridge.
Quarter Bridge Circuit:
Only one active strain gauge (Rg) is used as shown below. R3 is the inactive gauge, which is
identical to the active gauge but does not encounter any mechanical strains and is used for
compensating the temperature effect. The other two arms contain fixed resistors.

iLog Data Loggers User’s Manual Page 19/63
Half Bridge Circuit:
If the dummy gauge in the above figure is replaced by an active gauge, as shown below, the
resulting arrangement is called a half bridge. The half bridge has advantages for temperature
compensation and higher bridge sensitivity over the quarter bridge so that small strain levels can
be detected more accurately.
Full Bridge Circuit:
If four active gauges are employed in the circuit, the arrangement is called Full Bridge as shown
below. It is automatically temperature compensated when all four active gauges bonded on the
same material, and the highest sensitivity is obtained.
