3 TECHNICAL MAINTENANCE OF THE PRODUCT AND ITS COMPONENTS

3.1 Safety measures

After putting into operation, it is recommended to inspect the device periodically in order to
check:
 operability;
 compliance with the operating conditions;
 battery charge level;
 absence of external damages to component device parts.
When working with a charger connected to the 220-volt system at 50 Hz, the requirements set out
in the "Safety rules for the operation of electrical installations of consumers" are mandatory.
If the device is not used for a long time, the batteries should be turned off or removed. In doing so,
the batteries storage rules must be kept.
To work with the device are allowed those who have been instructed and certified for the II
qualification group for safety in working with electro-radio measuring devices.

3.2 Verification

The recommended verification interval is at least once a year.
The verification procedure (calibration; hereinafter - verification) applies to Flaw Detector
NOVOTEST UD3701 and establishes methods and means of their primary and periodic verification.

3.2.1 Verification and verifying instruments

During the verification, it is necessary to carry out operations and to apply verifying instruments
specified in Table 3.1. Main metrological and technical characteristics of verifying instruments are
specified in Table 3.2.
