1.1 Features of the logger
Congratulations on purchasing the Accsense VersaLog series 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 10 years of instantaneous logging operation when
sampling at interval of one minute.
Accsense VersaLog data logger can be manipulated by VersaLog 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.
Accsense VersaLog data loggers feature a wide sampling interval range from 20 milliseconds to
12 hours, providing an alternative to data acquisition devices and paper chart recorders.
Accsense VersaLog data loggers provide 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.
Accsense VersaLog data loggers also have an excitation control output used to switch the power
supply of the external transducer/transmitter.
Accsense VersaLog data loggers contain one internal thermistor channel, and seven external
process signal channels. The 16-bit analog-to-digital converter makes the measurements more
precise and accurate.
Accsense VersaLog data loggers also have a rugged, splash-resistant aluminum enclosure, and
internal electronics are protected against moisture ingress by conformal coating.
1.2 Approvals
All Accsense VersaLog Series data loggers are in conformity with the EN standard(s) listed
below:
EN 61000-6-2:[2005]
General standards –Immunity for industrial environments

Accsense VersaLog Data Loggers User’s ManualPage 7
EN 61000-6-3:[2007]
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 Accsense VersaLog 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
Although the Accsense VersaLog data loggers are weather resistant, the 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 ACCSENSE
VERSALOG.
1.5 Battery
The battery lasts in excess of 10 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 VersaLog 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.

Accsense VersaLog Data Loggers User’s ManualPage 8
1.6 Recalibration
Any Accsense VersaLog 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 VersaLog SiteView software.
VersaLog SiteView software provides two-point calibration for the most of the loggers.
1.7 Safety Warning
Maximum Input Voltage Range
For logger model: VL-DCV-2, VL-DCVC-HR, VL-TH, VL-TC:
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: VL-DCC-HR, VL-DCVC-HR:
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 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 Accsense VersaLog data logger is connected directly to the
ground of the input process signals and the ground of the external power supply (if
applicable).
