General Information
UNI (MP100) is a single sensor, portable, personal toxic gas monitor. It displays gas
concentration continuously on a big segment LCD. It also monitors STEL, TWA, peak and min
(for O2 only) value of the gas, and can be displayed on demand.
High、Low、STEL、TWA alarm threshold values are configurable. The shell is made of high
strength, durable material. Two key operation, simple to use. Sensor and battery can be replaced
easily. Calibration is also very convenient.

Using MP100
Turn the unit on
Press and hold the Right Key for 3 seconds, until LCD displays , buzzer beeps,
green LED flashes, then release the button, the unit is powered on.
Warm up sequence
After powered on, the unit enter warm up and self test sequence, show the firmware version as
follows:
If the sensor is not able to be identified by the instrument or is not installed into the instrument,
then the screen toggles between and .Otherwise, the
following values will be shown accordingly:
High alarm threshold value:
Low alarm threshold value:

TWA (time-weighted average) alarm threshold value:
Normal mode
Real time reading
The unit enter normal mode, start monitoring gas concentration and display on the LCD screen.
User can check some other values like STEL,TWA, PEAK, and MIN (for O2 only) by pressing the
Right Key.
STEL screen:
TWA screen
Peak screen
Press the Left Key to clear peak value
Press the Left Key again, peak value is cleared.

Config mode
In Config mode, user can do calibration, change parameters for the unit. In general, use the Left
Key to increase number or confirm, use the Right Key to move cursor or move to the next
programming item.
Enter Config mode
Press and hold the Left Key and the Right Key together for 3 seconds, then the unit enter Config
mode.
The Config mode is password protected, LCD displays to prompt enter
password. The screen displays , with one digit flashing in red, to let user input
password.
To input password, use the Left Key to increase the number, use the Right Key to move cursor.
After all four digits are input, the cursor will move to “OK”, use the Left Key to finish password
input and enter the Config mode.
If the digit input is mistaken, use the Right Key to move cursor between four digit and “OK” mark,
to change the input.
Sensor calibration
Before the unit can monitor gas correctly, it need to know the metric, this is done by zero
calibration and span calibration.

Calibration Process
1. Attach the Calibration Adapter over the inlet port on the front of MP100 by pressing it into
place.
2. Enter the calibration function, open the gas cylinder, press the Left Key, and start calibration
after countdown.
3. Take off the Calibration Adapter (according to the direction of the icon and suggest to make use
of the Calibration Adapter’s inlet), and complete calibration. When monitoring, never operate the
MP100 with the Calibration Adaptor attached. The MP100’s sensor operates by diffusion. If the
Calibration Adapter is attached during normal operation, inconsistent and lower-than-normal
readings will occur because of decreased concentration of the gas being monitored.

Zero calibration
Zero calibration is to get the base line for the sensor, it is done in fresh air. When LCD displays
, press the Left Key to start zero calibration. Unit will start 15 seconds
count-down, after count-down is finished, zero calibration result will be displayed on the LCD,
pass or fail .
If user don’t want to do zero calibration during 15 seconds count, press the Right Key, LCD
displays , zero calibration is aborted.
Span calibration
Span calibration is to get the metric of the sensor to the gas, it is done with a known concentration
gas. When LCD displays , apply the known gas to the unit, then press the Left
Key to start span calibration. Unit will start count-down, the count-down time depends on
different sensors ( normally is 60 seconds), after count-down is finished, span calibration result
will be displayed on the LCD, pass or fail .
If user don’t want to do span calibration during count-down, press the Right Key, LCD displays
, span calibration is aborted.
Change alarm limit
All the preset alarm limit: High, Low, STEL, TWA, can be changed. When LCD displays:

MP100 User’s Guide

, , , , press the Left Key
to change the corresponding alarm limit, the value change process are similar.
First the current setting value is displayed, with the first digit flashing: .
Use the Left Key to increase the current digit, , cycle from 0 to 9.
Use the Left Key to move cursor to the next digit:
After all digits are done, use the Right Key to move cursor to “OK” symbol, ,
press the Left Key to confirm the changing.
* MP100 will show “Err”, if the input data is invalid as follows,:
- Low alarm setting is bigger than high alarm setting.
- High alarm setting is smaller than low alarm setting.
- Input data is bigger than measuring range.
Change span value
The span calibration preset value can also be changed, the change process is similar with the alarm
limit. But the new span will not take effect until user successfully completes a span calibration
next time.
*MP100 will show “Err”, if the input data is invalid as follows:
- Span setting is smaller than 5% measuring range or bigger than measuring range.
- For Oxygen sensor, span setting is bigger than 19.0 .

Change display unit
MP100 supports different gas unit, to change gas unit, when LCD toggles between
and , press the Left Key to change gas unit. The supported
units for current sensor are all displayed on the LCD, the current selected unit is blinking. Use the
Right Key to change unit, use the Left Key to confirm selected gas unit.
Vibrator enable/disable
The vibrator consumes a lot of power, it can be disabled to save battery power, to extend the
battery life.
When LCD toggles between and , press the Left Key to
change the vibrator enable/disable status. The current vibrator status is displayed on the LCD,
toggling between and if the vibrator is enabled, or toggling
between and , if the vibrator is disabled. Use the Right Key
to change the enable/disable status, and use the Left Key to confirm the change.
Power on zero enable/disable
Sensor base line may have some change due to environment (temperature, humidity…), that will
require a zero calibration. MP100 can do zero calibration every time unit is powered on, this
feature can be enabled/disabled.
When LCD toggles between and , press the Left Key to go to
change power on zero calibrations enable/disable status. The current enable/disable status is
displayed on the LCD, use the Right Key to change, use the Left Key to confirm the change.

Maintenance
Replace the battery
When the battery’s charge is low, LCD displays , battery low alarm will be
triggered once every minute. User need to replace the battery.
When battery is dead, LCD displays , battery dead alarm will
be triggered once every second. User need to replace the battery.
To replace battery:
1） Turn off the MP100.
2） Place the MP100 face down on a soft surface.

5） Slide the battery out of its compartment.
6） Place the new battery into the compartment with its “+” end oriented toward the “+” on the
printed circuit board.
7） Plug the buzzer connector and install the top cover back.
8） Install the screws back from the back cover.
Replace the sensor filter
A “peel-and-stick” filter should be used on the MP100 in order to keep debris from fouling the
sensor. Sheets of 5 filters are available. When the filter appears dirty, replace it with a new one and
dispose of the dirty filter.
1) Turn off the MP100.
2) Place the MP100 face down on a soft surface.
3) Use a screwdriver to loosen each of the four screws by turning them counterclockwise.
4) Remove the top cover after carefully unplug the buzzer connector.
5) Peel a filter from the sheet and center it over the sensor. Gently press down.
6) Plug the buzzer connector and install the top cover back.
7) Install the screws back from the back cover.
Maintenance should be performed only by a qualified person who
has proper training and fully understands the contents of the manual.

Replace the sensor
MP100 models are designed so that you can easily change the sensor.
1) Turn off the unit.
2) Place the MP100 face down on a soft surface.
3) Use a screwdriver to loosen each of the four screws by turning them counterclockwise.
4) Remove the top cover after carefully unplug the buzzer connector.
5) Replace the old sensor with a new one. Make sure the pins are not bent or corroded . Align the
pins to the corresponding holes and push the sensor straight in . The sensor should fit flush
against the printed circuit board.
6) Plug the buzzer connector and install the top cover back.
7) Install the screws back from the back cover.
Sensors are not interchangeable. Use only mPower’s
sensors, and use only the sensor type specified for your MP100 monitor.
Use of non-mPower’s components will void the warrenty and can
compromise the safe performance of this product.
