Sleep Mode - Ahlborn ALMEMO 6290-7B Operating Instructions Manual

Measuring Point Scan

7.2.5 Sleep Mode

As one completely recharged battery only allows for an operating time of 90
hours at maximum (even with large print cycles) it is possible to operate the
instrument with the built-in printer in sleep mode for long-term monitoring.
Within this power saving mode the device will switch off after each measuring
point scan and will automatically switch on for the next measuring point scan
after the cycle time has expired.
As a result, it is possible to acquire up to 5,000 cycles in print mode and up to
15,000 cycles in plot mode. The print cycle must be set to more than 1 minute.
The cyclic output is, at first, started as usual (see 7.2.2).
The following steps must be performed for an operation in sleep mode:
1. A print cycle with a duration of 1 minute at minimum must be entered.
2. The measurement is started using the key START/STOP within the function
MEASURE.
3. Switch-over to sleep mode
in function MEASURE by using the keys ENTER,  (SLEEP).
Sleep Mode:
Before the instrument will automatically switch off, the display will indicate
´SLEEP ON´ for one second when it has been programmed properly.
If the programming is not correct, the display will indicate ´SLPErr´ and
corresponding error messages will be provided as output to the printer:
Sleep mode is not possible:
Cycle is not started.
Cycle must be longer or equal to 1 minute.
or Paper feed must be less than 20mm/h.
4. Within the set cycle the instrument will automatically switch on,
perform a measuring point scan,
display ´SLEEP ON´ and the measured values,
and then switch off.
5. Switch-over to active operation
The instrument must be switched on again by using the key ON/OFF.
After a measuring point scan the measurement will be continued in normal
mode.
6. Terminate the measurement by using the key START/STOP.
