K-TYPE THERMOCOUPLE PROBES
When the batteries are inserted and no power adapter is connected,
the meter can recognize different batteries charge levels.
1. Fully charged batteries. The backlight and printer can be
enabled.
2. Weakening batteries - "LOBAT" symbol blinks on LCD. The
backlight and printer are automatically disabled and it is not
possible to enable them until new batteries are inserted or an
external power adapter is connected.
3. Weak batteries - "LOBAT" symbol stays still on lower LCD.
Backlight and printer are disabled and meter can work for about
20 hours. If in Timed logging mode with the power down
function enabled this time can be longer.
4. Dead batteries - LCD shuts off. The instrument stops working to
avoid erroneous readings.
Note It is not possible to activate backlight and printer when the
instrument is in a low battery condition. If the user attempts to
enable these functions without replac-
ing the batteries or connecting the
external power adapter, the meter will
show "batt" on LCD.
Battery replacement must only take place in a non hazardous area
using 1.5V alkaline AA type batteries.
In order to replace run down batteries, sim-
ply remove the two screws on the rear cover
of the instrument and replace the four 1.5V
AA batteries with new ones, paying atten-
tion to the correct polarity.
A 12VDC power adapter can also be used to
power the unit (see the accessories para-
graph).
Note: The instrument uses the following configuration.
The HANNA HI 710005 or HI 710006 voltage adapters are recom-
mended, because they use the proper polarity configuration.
However, the meters can be used with other adapters. In this case,
remember to check the correct polarity of the adapter before connect-
ing it to the meter.
