HI 92701, HI 92704, HI 92801 and HI 92804 are factory pro-
grammed to automatically diagnose a fault. This is displayed with
error codes on the LCD.
Error codes:
PEr0, PEr1, PEr2 = Short circuit on the system, the meter should be
returned for repair (see Warranty section).
PEr3 = Printer mechanism fault - repair needed (see Warranty
section).
PEr4 = Printer clutch jammed - reset the printer (see page 27).
PEr9 = Printer jammed - reset the printer (see page 27).

MEMORY ORGANIZATION

MEMORY ORGANIZATION
MEMORY ORGANIZATION MEMORY ORGANIZATION MEMORY ORGANIZATION
Capacity:
16,000 data samples, divided into 16 pages.
Data capacity per page:
1000 data samples with 1 channel monitored;
500 data samples with 2 channels monitored (four channels versions only);
250 data samples with 3 or 4 channels monitored (four channels versions only).
Each time a new logging period starts, it automatically starts from a
new page.
If "LOGGING" is still on, and the available page is "0" the meter will
overwrite the first LOT DATA in the existing memory. During logging
the meter automatically returns to the oldest page in the memory
and if it contains data, it will overwrite. In this case the first log will
not correspond to the oldest set of data
It is recommended to periodically "clean" the memory. Save the data
in a PC if you need to keep a record and then disconnect the batteries
for about 1 minute. If you do this, remember to set the date and
time, once the batteries have been connected again.
ATTENTION
Data is stored in memory until the batteries are removed.
To replace batteries without loosing data, plug the adapter in and
proceed with battery replacement as described below. Only once
batteries have been replaced it is possible to unplug the adapter
without loosing the stored data.
