After upgrading the software, if a firmware upgrade is required it will be applied automatically when the
upgraded Instrument_Manager application is started. In that case do not disconnect the instrument until
the upgrade is completely over. Failure to do that will place the instrument in a state where it no longer
works.
Note:
A firmware upgrade will not lose any recorded data, but may reset some of the instrument's
settings.
Note:
When upgrading the instrument's firmware always make sure that only one instrument is
connected to the PC at a time.
11 Troubleshooting
11.1 USB Power Limitation
In some instances a PC will not allow the instrument to connect to one of its USB ports because it
cannot provide the battery charge current requested by the instrument. If you suspect that this may be
a factor, try connecting the instrument to the output of an externally-powered USB hub that is capable
of providing a full USB load (500 mA). Alternately, recharge the instrument using a USB charger.
11.2 USB Driver Installation
If the Instrument_Manager application is unable to communicate with the meter it may be
because the USB driver failed to install properly. To check the USB driver installation follow the
procedure below:
1. Disconnect the USB cable.
2. If necessary take the PC out of stand-by.
3. Reconnect the instrument to an available USB port on the PC.
4. Make sure the charge LED lights-up green (charged) or yellow (charging). If not, make sure
that the PC's USB port is functional and that the USB cable is not damaged. If necessary try
on a different PC, and/or with a different USB cable. The charge LED is just an indication that
the port is powered. It should light-up, even if the USB driver is not installed properly.
5. Make sure that the operation LED starts blinking. If not go to step 6.
6. Open the Device Manager on the PC. This is usually found in Control Panel – System and
Maintenance.
7. Just after connecting the instrument to the PC, observe that the Device Manager window
refreshes.
8. Verify that an item named DDCI Platform or ABC-Mems has been created in the list of
devices.
9. If an unknown item appears, or an item named DDCI Platform or ABC-Mems is found but has
an exclamation mark (indicating a problem) beside it, disconnect the device and try re-installing
the driver (see step 10).
