Important! The DM-X900 is a complex instrument. Please read
operating instructions before operating.
Getting started with your DM-X900
What is Included
Your DM-X900 package will contain:
a. DM-X900 Paranormal Data Acquisition Meter
b. USB Charger Adapter
c. USB Cable
Overview
The DM-X900 is an advanced instrument specifically designed for the collection
of data in paranormal investigations. The DM-X900 allows the operator to
collect and store correlated, time stamped data from multiple sensors and
audio simultaneously to aid in proving or disproving paranormal activity. Over
11 hours of sensor data and audio can be recorded and later downloaded to a
computer for data analysis via USB. Your DM-X900 utilizes state of the art
digital signal processing and touch screen technology that makes it one of the
most advanced paranormal meters on the market today.
Note: The touch screen on the DM-X900 is a pressure
sensitive membrane and requires more pressure than you
may be used to with the capacitive touch screens on cell
phones and tablets.

Operating your DM-X900
First Time Use
Before turning on your meter for the first time, it is important that the battery
has a good charge. It is recommended that you charge the meter with the
included USB charger wall adapter and USB cable. You may also use a USB
connector on a computer as a charging source.
Step 1. Insert Temperature Sensor
1) The temperature sensor for the DM-X900 Type B meter is a
detachable low mass thermistor that plugs into the 2.5mm jack
on the front of your meter. Insert the temperature sensor into
the jack. The temperature sensor can be removed for storage
and can be replaced if it is broken. Separate replacement
sensors can be purchased from Dark Matter Technology.
Please follow these start up instructions before turning on your
meter.
Note: Once USB Access Mode is selected in the Setup Menu,
you cannot exit out of USB Access Mode without turning the
meter off.

Step 2. Charge the battery
2) Plug the USB charger wall adapter into an acceptable A.C. wall
socket.
3) Plug the provided USB cable into the charger and the meter’s
USB connector. The amber charge LED should light and charging
will commence.
4) It is likely that your meter arrived with nearly a full charge, but
charging may take up to 10 hours if the battery is exceptionally
low. When charging is complete, the amber LED will go out.
Your meter is now fully charged.
5) While you are charging, you can use this time to turn on the
meter and set it up. The meter will run from the USB power
source while the battery is charging.

button should light up red
and a banner screen should
appear on the LCD panel like
Figure 2.

2) A progress bar will advance as
the processor initializes
turning blue, green, yellow,
and then red. Next, the
sensor display screen will
appear.
3) The ON/OFF button light
should go out.
Step 4. Set up your meter
It is likely that most of the
settings will be properly set up
on your meter when it arrives.
However the following steps
ensure that it is in fact properly
set up and ready for use. The
recommended settings in the
following steps are common
settings and you may wish to
modify them later to suit your
preferences.
1) Press the button on
the touch screen. The blue
menu screen shown in
Figure 3 should appear.
