General Information

MP342 is the MUNI Calibration and Bump Test CaliCase. All records of calibrations and bump tests performed on the CaliCase are stored in its USB disk. The CaliCase includes internal rechargeable batteries and is portable for remote use. CaliCase comes with the following standard features

• Ability to bump test, calibrate, set configurations, and upgrade firmware for MUNI
• 1 to 4 MUNIs can be tested at once.
• Rechargeable internal battery, up to 1500 bump tests before recharging
• USB flash for bump test and event log storage for up to 1 million bump tests
• 1 Internal gas cylinder plus 2 inlets: one for extra gas, one for fresh air
• 2 Buttons: one for calibration, one for bump test

This Manual describes only the operation of the MUNI 4-Bay CaliCase docking station and it is assumed that the operator is already familiar with the MUNI User’s Guide, including simple maintenance, firmware configurations, and mPower Suite software operations.

The interpretations of the various LED indicators are listed below.

Installation and Set Up

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.

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 a 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.

Power On/Off
Press and hold the Cal/button for about 3 seconds.

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
2. Click the Search button at 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 to enter an expiration date for Gas #2 even if no Gas #2 is used.
5. Click the “Write” button on the lower right to send the information to the
6. Click on the MUNI Info tab and click “Write” in the middle of the No parameter changes need to be made here.
7. Click on the CaliCase icon in the left panel to open its Configuration
8. Enter other parameters and functions as listed below and click “Write” on the bottom

   2. Gas Inlet#1 – Set gas cylinder parameters of inlet 1 (Internal gas inlet)
   3. Gas Inlet#2 – Set gas cylinder parameters of inlet 2 (External gas inlet)
   4. Firmware Upgrade – Select a computer file to upgrade the CaliCase Obtain the latest firmware at Software Downloads | mPower Electronics Inc. (mpowerinc.com).
   5. Hibernate Timeout – The CaliCase automatically turns Default is 300 seconds.
   6. Maximum Bump time – The maximum time allowed for a Bump Can be set from 10-120 seconds. The default is 30 seconds.
   7. Maximum Purge time – The maximum time allowed for clearing the gas tubing after CAL/BUMP. Can be set from 0-60 seconds. The default is 30 seconds.

   10. Update Unit Config – If selected, the CaliCase will update the MUNI configuration when pressing the CAL or BUMP button (see Section 5.2).
   11. Update Unit Firmware – If selected, the CaliCase will update the MUNI firmware when long pressing the BUMP The MUNI firmware must first be downloaded to the computer and the file path selected on the UDisk MUNI Info tab (see Section 5.2). Note that MP342 is only compatible with MUNI firmware version 1.0.9 or later.
9. Turn off the CaliCase by holding down the Cal Insert the UDisk into Port [14] and then turn on the CaliCase to automatically load the UDisk parameters onto the CaliCase.

Calibration Parameter Priority

When a calibration is initiated, the CaliCase uses the parameters stored in the CaliCase itself and overrides the values stored in 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 setup, 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.
