What
applications can it be used for?
All kinds of data recording: from 15,000 samples/second to 1 sample/hour
covering all science fields and industry applications.
What
are the HandyLog/MultiLog main advantages?
The HandyLog/MultiLog is a hand held data logger, equipped with a full keyboard
and display, to enable indoor and outdoor data collection. Its stored data can
be monitored / processed by a window based graphic software.
This cost effective system includes a variety of 30 sensors for measuring many
kinds of parameters in physics biology chemistry and industrial processes.
Is
there a Mac version of the DB Lab?
Yes, and it may be found in the download
section of this site.
Can
I use the MultiLog as a control unit?
Yes, the MultiLog has 3 digital control outputs. Any of the MultiLog's sockets
can be connected to either a sensor or a control switch (DT110, DT111). You
may connect two devices to one socket by using a splitter cable. For every output
you may define a control level, and when that level is crossed the MultiLog
activates a control device. The control switch can turn ON or OFF a load of
up to 220V/2A. Please refer to page 8 of the MultiLog's user-guide for more
details.
Can
I print data in the field?
Yes, the MultiLog is equipped with an Infrared transmitter. Using this transmitter
you may print out your last experiment's results on to an HP82240B hand
held printer. Simply press the PRINT icon on the MultiLog's keypad and aim the
IR eye at the receiver eye of the printer.
Can
the DBLab software work in a network?
Yes, provided that each terminal is equipped with a free serial communication
port.
Can
I duplicate the DBLab software?
The DBLab software can be duplicated and spread freely among your student, to
help them making home reports.
What
is the HandyLog/MultiLog battery life?
The HandyLog/MultiLog battery life is 100-150 hours, while working with most
of the 30 types of sensors.
Can
I retrieve the stored HandyLog/MultiLog data even when its battery is dead?
Yes, the HandyLog/MultiLog 128KB memory has an internal back up battery saving
the stored samples when the HandyLog/MultiLog is off or its battery is dead.
Turning on the HandyLog/MultiLog, or replacing its battery enables communication
with the PC software, and allows samples transfer to the PC computer.
What
other accessories do you have for the HandyLog/MultiLog ?
The HandyLog/MultiLog system offers the following accessories:
Can
I use sensors from other vendors?
Yes, we support most of the other vendors sensors, like the Vernier sensors.
How
can the sensor effect the HandyLog/MultiLog battery life?
Most of the sensors consumes very low power from the Handy-Log. Using those
sensors the data logger can work for hours on its 9V alkaline battery. There
are 3 sensors that consumes high power from the Handy-Log: Pulse, Force and
distance sensor. When using those sensors we recommend to connect the data logger
to an external 9-12V DC supply, otherwise the battery will go off in about an
hour.
Can
I define a new type of sensor, not included in the HandyLog/MultiLog list of
sensors?
Yes, provided that the sensor you are using meets the following conditions:
Why
do I see voltage units when sampling the Microphone?
The microphone is monitoring the sound wave shape, displayed in voltage units.
The sound level measured in decibel values is another mathematical description
of the sound amplitude.
I'm
sampling a sensor but seeing on the DBLab units of another sensor, what is wrong?
The DBLab software is assuming a wrong Data logging version. Press the "about"
in the DBLab menu and see the DB-525 version (V3 or V4). To get the data logger
version, turn it on. The version will appear on the left side of the LCD display.
In case the version numbers are not the same, use the communication setup from the DB-525 menu to reconnect the HandyLog/MultiLog. This action will update the DB-525 version in the DBLab.
During
a long logging the battery went down. Did I lose all samples till that point?
No, the samples are not lost, replace the 9V battery, turn the on data logger,
connect it to the PC and start downloading the samples to the DBLab software.
The data logger saves all samples till the moment its battery went down.
I
have connected the external supply, but the HandyLog/MultiLog will not turn
on. Why?
Please check if the external power supply provides 9-12V, and its plug has
a negative center.
How
can I set the HandyLog/MultiLog clock?
To set the HandyLog/MultiLog internal clock and calendar, connect the datalogger
to the PC serial port, and turn it on. Open the control panel from the DB-525
in the DBLab menu, and change one of the DB-525 logging parameters (like the
sensor type on input 1). This action updates the chosen parameter as well as
the clock and calendar in the data logger. The time and date information are
taken from the PC main clock.
I
start a new logging and the Data Logger stops immediately after. What is wrong?
First check if the sampling rate is so fast that the experiment is over in less
then a second. If this is not the reason replace the 9V battery and try again.
The Data Logger is monitoring the battery power during the logging. If the battery
voltage is less then 7.2V the logging is stopped automatically
There
is no communication between the MicroLog and the PC. What should I do?
Please perform the following tasks:
I'm
having problems to communicate with the HandyLog/MultiLog (from the PC), what
should I do?
Delete the file DBLab.INI from the WINDOWS main directory. Connect the HandyLog/MultiLog
to the PC serial port, using the serial cable. Open the DBLab software. The
communication setup dialog box will open.
If one of the port buttons is marked with an X press the "Try to connect" key in the dialog box, the DBLab should return the HandyLog/MultiLog version and the comm port used for communication with the HandyLog/MultiLog. In case there is a marked port, but the DBLab software is not able to communicate with the data logger (after you press the "try to connect" button) call your local dealer for technical assistance.
If no port is marked by X, it means this happens when your computer uses serial ports for internal modem, network PC cards. In this case it is recommended to call your local dealer for support. Yet before addressing the dealer please try the following: Turn off your PC. Turn it on again and enter the BIOS setup by pressing and holding the DEL key. In the BIOS setup choose "Integrated Periferals" and make sure that both "on board serial port 1,2" are enabled. If not select a combination of COM1 for serial port 1 and COM4 for serial port 2. Save the setting and exit the BIOS setup. Now try to set communication between the data logger and the DBLab.
Using
the Distance sensor, I get the "Low Bat" message in the HandyLog/MultiLog display,
what should I do?
It is recommended to use an external supply connected to the HandyLog/MultiLog
while working with the ultra sonic distance sensor. In some cases the connection
of the sensor cause a momentary loading of the HandyLog/MultiLog battery. This
will display "LOW BAT" on the HandyLog/MultiLog display. If, by pressing the
HandyLog/MultiLog keyboard the "LOW BAT" message disappears then the battery/external
power loading passed and the system is ready to operate. If the display still
shows the "LOW BAT" message, then the HandyLog/MultiLog power is low.
