2.4.3 POWER-SAVE MODE

When logging data, the OM-550 prolongs its battery life by automatically turning “OFF” (power-save mode) when unattended (no key closures detected for about 1 minute). If the OM-550 is in RUN mode it will wake and log data at the next appropriate time.

When the OM-550 is in the Programming and CAL modes it remains “ON”; and must be turned “OFF” manually.

2.4.4 LOW BATTERY OPERATION

The OM-550 continually checks the battery voltage and automatically turns “OFF” when the batteries are exhausted. Printing will then be inhibited (because the required power is not available) but the time, date, and cached data are retained.

If the batteries are exhausted while logging, the OM-550 will automatically stop, then turn “OFF”. Printing time is will also be prohibited and data will be retained.

To retrieve the data, connect the AC Power Adapter or the collected data will be lost if the batteries are removed. Connect the OM-550 to a PC and turn it “ON”. Now transfer the data as usual.

If the batteries become completely exhausted or removed the cached data is lost but all programming except the time and date is retained.

2.4.5 BATTERY CHECK

To check the battery voltage, disconnect the AC Power Adapter and press the VOLTS key while the units is “ON” but not running (logging data).

Figure 2-17

Fresh batteries typically read from 5.9V to 6.4V. Consider replacing the batteries when the readings fall below 5.0V. Readings near 4.5V show that the batteries are nearly exhausted.
