GPS time synchronization device connection
MI 2893/MI 2892/MI 2885 have the ability to synchronize its system time clock with Coordinated
Universal Time (UTC time) provided by externally connected GPS module (optional accessory - A 1355).
In order to be able to use this particular functionality, GPS unit should be attached to the instrument
and placed outside. Once this is done, GPS module will try to establish connection and get satellite time
clock. MI 2893/MI 2892/MI 2885 distinguishes two different states regarding GPS module functionality.
Table 127: GPS functionality
GPS module detected, position not valid or no satellite GPS signal reception.
GPS module detected, satellite GPS signal reception, date and time valid and
synchronized, synchronization pulses active
Once an initial position fix is obtained, instrument will set time and date to GPS + Time zone - user
selected in Set Date/Time menu (see figure below).
Figure 133: Set time zone screen
Table 128: Keys in Set time zone screen
Changes Time zone.
Confirms selected Time zone and returns to “GENERAL SETUP” menu.
When the time zone is set, MI 2893/MI 2892/MI 2885 will synchronize its system time clock and internal
RTC clock with the received UTC time. GPS module also provides the instrument with extremely
accurate synchronization pulses every second (PPS – Pulse Per Second) for synchronization purposes in
case of lost satellite reception.
Note: GPS synchronization should be done before starting measurements.
