3. Installation and Set Up
3.1 Charging
The charging port is located on the right side of the CaliCase. Connect the DC adapter to an AC
110~240V power supply (wall outlet). A full charge takes approximately 3 hours and lasts for up to
1500 unit bump tests.
3.2 Gas Connections
Thread the main gas cylinder into the internal demand-flow regulator (DFR) [12] C10 inlet fitting [13].
Once tightly connected, the gauge [10] will indicate the cylinder gas pressure. If needed, a second gas
can be connected to hose-barb port [9] using a separate DFR. We recommend that any soft tubing (e.g.,
Tygon) used for port [9] be kept as short as possible to minimize potential loss of calibration gas. The
MP342 CaliCase is compatible with all the gases for sensors offered with the MUNI monitors.
3.3 Power On/Off
Press and hold the Cal/ button for about 3 seconds.
3.4 Initial CaliCase UDisk and Software Set Up
Before the first bump or calibrations can be performed, the CaliCase must be configured to match the
sensor types on the MUNIs to be tested and enter the calibration gas concentrations and expiration
date(s). The calibration gas is set up on both the CaliCase itself and the removable UDisk thumb drive.
(The MUNI span concentrations do not need to match the CaliCase and UDisk values)
IMPORTANT!!The MP342 will not operate properly without the UDisk inserted in Port [14]!!
Only the UDisk provided by mPower will function correctly.

Connect the CaliCase to a PC using the Type A male-to-male USB cable at port [5]. Insert the UDisk
into a USB port on the computer. Use mPower Suite software to configure the gas concentrations and
other parameters. Download mPower Suite at Software Downloads | mPower Electronics Inc.
(mpowerinc.com). Also, it is best to have the latest firmware installed in both the CaliCase and MUNI,
as earlier firmware versions may not be fully compatible with each other.
Procedure
1. Launch the mPower Suite software.
2. Click the Search button at the bottom. The CaliCase, MUNIs and UDisk should appear listed in
the left panel.
3. Click on the UDisk icon to open the CaliCase Info window and enter the calibration gas names,
concentrations and units. Make sure that the gas types match those of the MUNI sensors.
4. Enter the gas cylinder lot number and expiration date, making sure that the expiration date is past
the current date (but not more than 3 years from the current date). Be sure enter an expiration date
for Gas #2 even no Gas #2 is used.
5. Click the “Write”button on the lower right to send the information to the UDisk.
6. Click on the MUNI Info tab and click “Write”in the middle of the screen. No parameter changes
need to be made here.
7. Click on the CaliCase icon in the left panel to open its Configuration panel.

Calibration Parameter Priority
When a calibration is initiated, the CaliCse uses the parameters stored in the CaliCase itself and
overrides the values stored the MUNI configuration. Therefore, the MUNI span concentrations do not
need to match the CaliCase and UDisk values. Each time the CaliCase is turned on, the calibration
parameters automatically get loaded from the UDisk onto the CaliCase and override the existing
CaliCase parameters. Therefore, if new values are programmed onto the UDisk via PC and inserted
into the CaliCase, the CaliCase must be turned off and back on for those UDisk values to take effect.
After the first set up it is not necessary to re-configure the CaliCase directly. The direct CaliCase
procedures listed above are only needed for a few items such as the Location name and syncing the
device time and date.
