1.1 Features of the logger
Congratulations on purchasing the PRECISE-LOG series data loggers! These portable battery
powered data loggers allow recording information and saving measurements to a 8MB flash
memory for later retrieval.
The internal lithium battery provides up to 10 years of instantaneous logging operation when
sampling at interval of one minute in stand-alone mode.
PRECISE-LOG data logger can be manipulated by SiteView Windows software for data
downloading, logging management, and property configuration. It has USB interface for local
communications and a WIFI module for remote access (PL-[x]W Series).
PRECISE-LOG data logger features a wide sampling interval range from one second to 12
hours.
The 16-bit analog-to-digital converter makes the measurements more precise and accurate.
Rugged, splash resistant aluminum enclosure makes it excellent in the harshest industrial
environment.
WIFI enabled version allows remote data monitoring and downloading.
1.2 Approvals
All PRECISE-LOG Series data loggers are in conformity with the EN standard(s) listed below:
EN 61000-6-1:[2007]
EN61000-4-2:2009
EN61000-4-3:2006/A2:2010
EN61000-4-4:2012
EN61000-4-5:2006
EN61000-4-6:2014
EN61000-4-11:2004
EN 61000-6-3:[2007]
EN Standards for WIFI module:

PRECISE-LOG Data Loggers User’s Manual Page 7/57
EN62311:2008
EN60950-1:2006+A11:2009+A1:2010+A12:2011+A2:2013
ETSI EN300 328 V1.8.1 (2012-06)
ETSI EN 301 489-1 V1.9.2 (2011-09)
ETSI EN 301 489-17 V2.2.1 (2012-09)
For WIFI enabled models:
Contains FCC ID:2ACZO-WIFI1232T
All PRECISE-LOG Series 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
PRECISE-LOG data loggers are designed to work 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 10 years when sampling at 1-minute intervals in stand-alone
mode. 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.

PRECISE-LOG Data Loggers User’s Manual Page 8/57
1.6 Recalibration
Any PRECISE-LOG data logger is supplied with all channels pre-calibrated and should not
require any further recalibration for a period of 12 months.
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: PL-V, PL-VW (WIFI enabled):
The logger is designed to measure single common ground DC voltages in the range up to 20
VDC. Any voltages over this range may cause permanent damage to the device.
Maximum Input Current Range
For logger model: PL-C, PL-CW (WIFI enabled):
The logger is designed to measure single common ground DC current in the range up to 50
mA. Any current over this range may cause permanent damage to the device.
External Power Supply
When using external power supply (via PC’s USB port 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 PRECISE-LOG data logger is connected directly to the ground
of the input process signals and the ground of the external power supply (if applicable).

Measure Resistance:
SiteView provides factory resistance equation for measuring the resistor’s value. In
Configuration dialog:
Choose Resistance equation:
Measure Temperature:
The simple way to measure temperature is by using built-in “Temperature” equation. You
select “Temperature” in “Equation” column:
Then you need to change temperature coefficient values by clicking “Change Coefficients”
button in “Action” column:

PRECISE-LOG Data Loggers User’s Manual Page 17/57
In the pop-up dialog enter new temperature coefficient values and click “OK” button.

PRECISE-LOG Data Loggers User’s Manual Page 18/57
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:
Once you have created your equation (for example YSI2252(YSI thermistor 44004)), you can
apply it to the channel:

Built-In Equations
Equation and Channel Type are two essential parameters to make sure the physical
measurement can be converted correctly.
An equation is a software functionality identified by its name of up to 16 characters. A built-in
equation is an equation provided by SiteView software to convert a measurement for a specific
channel type.
A channel must have an equation assigned to it in order to make the measurement conversion.
“Digit” built-in equation can be assigned to any channel type. If you assign “Digit” equation to
a channel the physical measurement will be the original digital value measured by ADC
(Analog-to-digital converter) hardware.
The following table lists all available built-in equations for all channel types:
