MF5 Service Manual

•
Connect the vacuum pump to the service seal checker plug so that a vacuum of 0.49
atmospheres is created inside the MF5 chassis. A vacuum of 0.49 atmospheres (50kPa)
inside the detector is equivalent to submersing the detector to a depth of 5m in water.
•
Turn off the vacuum pump and close a valve on the vacuum pump output, confirm that the
pressure (in the MF5) doesn't drop below 50kPa (0.49 atm) after one (1) minute.
•
When the detector chassis can maintain a vacuum of 50kpa for one minute without leaking
(decrease in vacuum) it will be waterproof to a depth of 3m.
•
If the vacuum decreases rapidly there is a large leak, like a seal not fitted, if the vacuum
decreases slowly there is a small air leak. Check seals and O rings for possible leaks and
retest.
•
Remove the Service Seal Check Plug from the MF5, insert the Torx T20 screw into the
detector making sure it has an O ring (on the screw).
6 Software Upgrade.
a. The MF5 metal detector can have its internal software upgraded. When a software
update is available Minelab will create and distribute an application to automate the software
update process, referred to as the MUU (Minelab Update Utility).
b. Requirements, for conducting a software upgrade on the MF5:
•
Windows PC with; Windows 10 operating system, USB 2.0 port, minimum 50 MB of hard
drive space, minimum 20 MB of RAM.
•
Cable, Earset Data 3004-0300.
•
Software, MUU (Minelab Update Utility)
c. MF5 software update procedure:
•
Load the MUU onto the windows PC. When an update is available Minelab will host it on
our webpage for download or it will be supplied directly to the customer requiring it.
•
Connect the Data cable to the MF5 earset connector and a USB 2.0 connector on the
windows PC.
•
Run the MUU.
