HT ITALIA HT82 Portable Digital Phase Sequence Indicator
SAFETY PRECAUTIONS AND PROCEDURES
This meter is in compliance with safety standards IEC/EN61557-1 and IEC/EN61010-1 related to electronic measuring instruments. For your own safety and to avoid damaging the instrument follow the procedures described in this instruction manual and read carefully all notes preceded by this symbol . When taking measurements:
- Avoid doing that in humid or wet places – make sure that humidity is within the limits indicated in § 6.2.1.
- Avoid doing that in rooms where explosive gas, combustible gas, steam or excessive dust is present.
- Keep you insulated from the object under test.
- Do not touch exposed metal parts such as test lead ends, sockets, fixing objects, circuits etc.
- Avoid doing that if you notice anomalous conditions such as breakages, deformations, fractures, leakages of battery liquid, blind display etc.
- Be particularly careful when measuring voltages exceeding 20V to avoid risk of electrical shocks.
The following symbols are used:
CAUTION – refer to the instruction manual – an improper use may damage the
instrument or its components.
- Double insulation
- AC Voltage
PRELIMINARY
- This instrument has been designed for use in environments of pollution degree 2.
- It can be used for testing the phase sequence on installations of overvoltage CAT IV 300V and CAT III 600V to the ground.
- When using the instrument always respect the usual safety regulations aimed at protecting you against the dangerous electric currents and protecting the instrument against incorrect operations.
- Only the leads supplied with the instrument guarantee compliance with the safety standards in force. They must be in good conditions and, if necessary, replaced with identical ones.
- This instrument is not suitable for measurements of non sine wave voltage.
- Do not test or connect to any circuit exceeding the specified overload protection or under environmental conditions exceeding the limits indicated in § 6.1.1 and § 6.2.1.
DURING USE
We recommend carefully reading the following recommendations and instructions:
CAUTION: An improper use may damage the instrument and/or its components or injure the operator.
When the instrument is connected to measuring circuits never touch any unused terminal.

SUPPLY VOLTAGE
The instrument is self powered by the mains.
STORAGE
After a period of storage under extreme environmental conditions exceeding the limits mentioned in § 6.2.1 let the instrument resume normal measuring conditions before using it.
OPERATING INSTRUCTIONS
CAUTION: Do not test or connect to any circuit exceeding the specified overload protection. Do not attempt to measure higher voltages to avoid electrical shocks or damages to the instrument.
- Connect the test cables by following their numbering.
- Apply the relevant alligator clips to the free ends of the cables.
- Connect the alligator clips to the electrical mains.
- The instrument shows:
- The connected phase cables, L1, L2, L3 referred to the relevant inputs (two cables have to be connected at least).
- The phase sequence: the letter “R” with a clockwise arrow indicates the correct phase sequence, the letter “L” with a counterclockwise arrow indicates the incorrect phase sequence
