Hanna Instruments HI 91610C - Manual (Page 15)

29 28
HI 9161 and HI 91610 are factory programmed to automatically
diagnose a fault and inform the user by displaying an error code on
the LCD.
Error codes are:
PEr0, PEr1, PEr2 = Short circuit on the system, the meter should be
returned for repair. Contact your dealer.
PEr3 = Printer mechanism fault. Contact your dealer.
PEr4 = Printer clutch jammed - reset the printer (see page 31).
PEr9 = Printer jammed - reset the printer (see page 31).
SELF-DIAGNOSTIC FUNCTIONS
Capacity: 8000 sample data, divided into 16 pages.
Capacity per page: up to 500 data.
Each time a new logging mode is entered, the meter automatically goes
to the next available page. Once all 16 pages are used up, the meter
will overwrite the first lot.
During logging, the meter automatically returns to the oldest page in
the memory and if it contains data, it will overwrite it. In this case the
first log will not correspond to the oldest set of data.
It is recommended to periodically “clean” the memory. Save data into a
PC if you need to keep a record and then remove the batteries for about
1 minute. Remember to reset time and date, once the batteries have
been reinserted.
ATTENTION
If batteries need to be replaced and data is not to be lost, power the
meter through a 12 Vdc adapter before proceeding with battery
replacement.
Once batteries have been changed, the external power supply can be
disconnect without losing the previously memorized data.
MEMORY ORGANIZATION
(HI 91610 only)
When the batteries become weak,
the "LO BAT" indication is displayed
to warn the user.
Battery replacement must only take place in a safe area and using
using four 1.5V AA alkaline batteries.
In order to replace the batteries,
remove the two screws on the rear
cover of the instrument and replace
the four batteries with new ones,
while paying attention to the correct
polarity.
A 12 Vdc power source can also be used to power the unit.
Note:
The instrument uses the following configuration.
It is recommended to use the HANNA HI 710005 or HI 710006
voltage adapters with the proper polarity configuration.
HI 9161 and HI 91610 can also be powered through other 12 Vdc
adapters. Always check the correct polarity of the adapter before
connecting it to the meter.
