GDD Instrumentation MPP-EM2S Plus Instruction Manual page 59

• In Bluetooth operating mode, check if a Bluetooth Incoming Port (COM1 to COM9) has been
configured. This Incoming Port could be in conflict with the Port used by your MPP probe.
• Check if the probe is ON.
• Make sure that AA batteries are sufficiently charged. The Initialization process requires much
power. If the probe batteries are not fully charged, the program will not be able to initialize.
17.2 Errors during the measuring process
Problem:
After initialization, the readings seem to be unstable.
Solutions:
• As mentioned in the Warnings on the first page of this manual, it is highly recommended that you
leave the probe ON for one hour before taking the first measures.
• If it is impossible to wait for one hour before taking measurement, re-initialize the probe
frequently (see Section 10.3 – Re-Initialization).
