CONGRATULATIONS WITH YOUR NEW MICROSENSOR MULTIMETER!
The Microsensor Multimeter is a powerful and versatile four-channel microsensor amplifier which can
be used with all Unisense sensors and electrodes.
Overview
The Microsensor Multimeter is a digital microsensor amplifier with automatic sensor detection,
making the connection of the sensors ‘plug-and-play’. The user interface consists of a keypad and a
graphical OLED display, allowing the user to view signals, adjust signal gain and offset, etc. directly on
the instrument. The Microsensor Multimeter can be used as a stand-alone instrument or signals can
be transferred directly to a PC using a Unisense SensorTrace PC program.

inStallatiOn and Setup
Operating and setup cOnditiOns
The Microsensor Multimeter is a laboratory instrument.
Temperature 0°C to 50°C
Calibration The Microsensor Multimeter is offset calibrated on the four channels as well as
the two analog channels
Power Batteries, 8 x 1.5 V (AA) batteries
External voltage 9V (5-28V)
Mains supply 50/60Hz, 230/110V
One battery package at a time can be exchanged while operating the Micro-
sensor Multimeter.
If mains supply is disconnected battery supply will continue operation.
Note: Ensure mains supply is grounded.
Hardware version, firmware version, and serial number are available from the About Tab in the
Microsensor Multimeter interface.
Select your preferred power supply, e.g. AC, by inserting the power cable into the mains supply and
making sure that the cable is plugged into the AC socket of the Microsensor Multimeter.

inStalling the micrOSenSOr multimeter
1. Install the relevant software, SensorTrace Logger, SensorTrace Proling, or Sen-
sorTrace Rate (latest version can be downloaded via www.unisense.com) on your
computer.
NOTE. Windows XP users must make sure they are running .NET framework
version 4.0 or higher. If this is not the case an upgrade must be made - please
contact Unisense.
2. Connect the Microsensor Multimeter to the computer. The Microsensor Multime-
ter is recognized and you are asked for the driver les. These are located on the
enclosed CD.
getting Started
Sensor LEMO connection
OLED display
Key pad with Select and arrows for operating the Multimeter
1. Connect the sensor to the Microsensor Monometer. Some sensors are automati-
cally recognized (please see list under “compatibility”) and should appear in the
display next to the channel number to which it is connected, properly polarized.
If you are using a sensor which is not automatically recognized OR any sensor
with a BNC connection via a BNC-LEMO adapter, the sensor is recognized as
“sensor for manual settings” and you are required to adjust the polarization on
the channel manually (please consult the relevant sensor manual for the right
polarization value).
2. Optional use of grounding cable - with amperometric microsensor only.Use of
grounding cable may in certain environments improve signal-to-noise ratio and
overall data quality.
Connect grounding cable on the back side of the Microsensor Multimeter
Important: If mV sensors (redox or pH on Ch 3) or NO2
-or NO3 - sensors
are in use grounding cable must be omitted.
3. Calibrate the sensor. Please consult the relevant sensor and software manual for
details.
4. Start the measurements.
Note: do not unplug the USB connection during operation. In case of lost connectivity restart the
application.
Note: keep the default display power settings to protect the OLED screen.

Operating the MicrOsensOr MultiMeter
All movement between tabs and menu
options is performed by pressing
the select and arrow keys next to the
display.
• To select a tab or menu point, press
Select.
• To adjust a menu point, press the up
and down arrow keys.
• To exit a menu point and go back to
the menu, press the left arrow key.
adjusting the pre-aMplificatiOn
You may need to adjust the pre-amplification range of the sensor. This is done in the Measurement
tab on the Microsensor Multimeter by selecting the relevant sensor. The appropriate range is the
lowest range that can accommodate the highest signal to be measured. The range 1 mV/pA is
selected per default. If the expected
maximum signal in this range exceeds
4500 mV, the range should be changed
to 0.1 mV/pA. If the expected maximum
signal is less than 500 mV in the 1 mV/pA
range, then the 10 mV/pA range should
be selected.
cOmpatibility
sensOrs
The Microsensor Multimeter can be used
only with sensors with LEMO connec-
tions. Adaptors are available for sensors with BNC connections.
In the standard configuration, the Microsensor Multimeter has amperometric channels on channel 1
and 2, a potentiometric channel on channel 3, and a temperature channel on channel 4. For custom
configured instruments, please refer to your order confirmation for channel setup.
Amperometric sensors: O2, H2, H2S, N2O, NO, NO2
-, NO3 -, Flow, Diffusivity, APOX, TPOX, STOX,
Potentiometric sensors: pH, Redox
Temperature
Sensors that are automatically recognized and polarized: O2, H2S, pH, Redox, Temp.
All other sensors AND all BNC sensors connected via an adapter are recognized as “Sensor for manual
setting” and polarization is set manually. Please refer to the relevant sensor manual for polarization
values.

sOft ware
The Microsensor Multimeter can be used with SensorTrace Logger, SensorTrace Profiling and Sensor-
Trace Rate software. Unisense SensorTrace Suite software is compatible with Windows XP, Vista,
Windows 7 32/64 bit and Windows 8/8.1.
NOTE: Windows XP users must make sure they are running .NET framework version 4.0 or higher. If
this is not the case an upgrade must be made - please contact Unisense.
auxiliary equipment
Unisense can provide you with solutions for a range of experimental setups, including bulk measure-
ments, microprofiling and micro-respiration. Depending on your measuring requirements, you may
need additional equipment for positioning, calibration, sample fixation, etc.
