When installing the batteries into the battery compartment, make sure that the polarity
of batteries is correct. Close the battery compartment.
WARNING
Incorrect installation of the batteries may lead to damage to the
Analyzer or to the batteries. If the alkaline batteries are used, is strictly
prohibited to connect the IT-088 to the external DC power source, as the
batteries of this type cannot be recharged.
To charge the batteries without removing them from the Analyzer, connect the external
DC power source included in the set, and power it. The batteries will keep recharging even
if the IT-088 is switched off. The backlight of
«STD BY»
button indicates that the power
from the source is being supplied. In this case the full recharge will take from 12 to 14
hours. It is highly recommended to only recharge the batteries that are fully run-down. You
should charge batteries using the external power source once every 2 – 3 months in order
to equalize the charge of batteries and thus increase their useful life.
The circuit design of battery charge provides the shut down of current in case the
resultant battery charge is less than 5 V. In case the batteries are completely run-down, it
is possible for the charge to fail to switch on. The voltage of the batteries can be checked
using the IT-088 self-test program (section 4.6.3) when powered from external DC power
source. The charge of the batteries shall be no less than 5.5 V. In this case the batteries
must be removed from the Analyzer in order to be recharged separately or disposed.
5. MAINTENANCE
Required maintenance is limited to observation of instructions related to proper
operation, storage, and shipment, which are supplied in this Manual and also minor
defects correction.
Perform preventive inspections covering check of controls, reliability of the assembly,
and the keypad condition after the warranty period has expired and annually since then.
6. TROUBLESHOOTING
Defect detection
: After the IT-088 is switched on, nothing is displayed on the screen
and there is no blinking backlight.
Possible reason
: Extremely low charge, malfunction, or lack of one or more of the
batteries.
Methods of correction
: In order to check the IT-088 condition, connect the network
power supply unit. If the Analyzer switches on, then the battery voltage has to be tested by
means of the self-checking function (section 4.6.3). Low voltage (< 6 V) is an evidence that
a battery (or a number of batteries) is discharged. Voltage that is higher than normal (>
8V) indicates malfunction or lack of one or more batteries. The batteries have to be
charged in case they are low (section 4.12) or replaced if they are malfunctioning.
Possible reason
: Firmware failure.
Methods of correction
: Install the firmware from your computer (section 4.11.1). If the IT-
088 starts working after this has been done, the firmware should to be saved in NVRAM of
the Removable Module without switching the Analyzer off (section 4.11.2).
Defect detection
: When the IT-088 is switched on, the following message is displayed:
Removable Module not found.
Possible reason
: Firmware failure in Removable Module.
