MEMORY ORGANIZATION

HI 98801 - HI 98804 only

Logged data are stored in the internal EEPROM and are retained even

if batteries and external power are disconnected.

MEMORY CAPACITY

• 14000 data samples divided into 16 lots (lots 01 to 16)

• 9999 data samples maximum for a single channel

• 300 data samples for the Log on demand (lot 00).

TIMED LOG (lots 01 to 16)

Each time a new logging period starts, it automatically starts from the

next available lot. If the last lot was the 16th, the new logging period

restarts from lot 01 overwriting previously logged data.

When Timed logging memory is full, the meter overwrites the oldest

lot data progressively reducing the old lots. In this case the starting

time, date and the dimension of the old lot are updated.

Note: The oldest lot data are erased without any warning message.

Note: Timed logging memory can be entirely erased through the

setup code 06.

If the meter is powered only by the external power supply and there is

a temporary power black out during logging, when power returns, the

logging continues normally if no samples have been lost, otherwise

the current lot is ended and a new lot starts. If printer is enabled, the

"...Stop..." message will be printed. In any case, during scrolling the

former lot will be preceded by the "Interrupted Lot" message and the

latter by "Continuation Lot" to indicate the interruption.

LOG ON DEMAND (Lot 00)

When Log on demand data area is full the meter shows the "FULL"

message to warn the user that the data are not stored in memory.

Erase the memory area through setup code 05 to continue logging

data on demand.
