1. SAFETY PRECAUTIONS AND PROCEDURES
The word “meter” in this manual means generically both the model HT9014 and the model
HT9015 except notation specifically indicated. The meter complies with IEC/EN61010-1.
For your own safety and in order to avoid damaging the instrument, you’re recommended
to keep to the instructions contained in this manual and read carefully all the notes
preceded by the symbol .
Take extreme care for the following conditions while measuring:
• Do not measure voltage or current in humid or wet environment.
• Do not use the meter in presence of explosive gas (material), combustible gas
(material), steam or dust.
• Insulate yourself from the object to be tested.
• Do not touch exposed metal (conductive) parts such as test lead ends, sockets, fixing
objects, circuits, etc.
• If you detect anomalies of testing end (metal part) and attachment of the meter such as
breakages, deformations, foreign substances, no display, etc., do not take any
measurement.
• Measuring voltage over 20V as it might cause human body electricity conduction.
The followings symbols are used on meter and in this manual:

1.1. PRELIMINARY
• This apparatus has been designed for use in an environment of pollution degree 2.
Indoor use.
• It measures CURRENT and VOLTAGE on CAT IV 600V and CAT III 1000V plants. For
measurement categories please see § 1.4.
• You must comply with the usual safety regulations aimed at protecting you against the
dangerous electric current and protecting the instrument against an incorrect operation.
• Only the leads supplied with the instrument guarantee compliance with the safety
standards. They must be in good conditions and they must be replaced, if necessary,
with an identical model.
• Do not test or connect to any circuit whose voltage or current exceeds the specified
overload protection.
• Make sure that the batteries are installed correctly.
• Before connecting the test probes to the installation, check that the function selector is
positioned on the required measurement.
• Make sure that the LCD and the range indicator show the same as the function
desired.
