PRECAUTIONS AND SAFETY MEASURES

The accessory has been designed in compliance with IEC/EN61557 and IEC/EN61010-1 guidelines relevant to electronic measuring devices. For your safety and to prevent damaging the accessory, please strictly follow the procedures described in this manual and read carefully all notes preceded by symbol . Before and after carrying out measurements, observe the following instructions:

• Do not carry out any measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are present, or in dusty environments.
• Avoid any contact with the circuit under test if no measurement is in progress.
• Avoid any contact with exposed metal parts, with unused measuring probes, circuits, etc.
• Do not carry out any measurement in case you find anomalies in the accessory such as deformation, breaks, substance leaks, absence of display on the screen, etc.
• Pay special attention when measuring voltages higher than 25V AC, since a risk of electrical shock exists.

In this manual, and on the accessory, the following symbols are used

• Warning: observe the instructions given in this manual; improper use could damage the accessory or its components.
• High voltage danger: electrical shock hazard
• Accessory with double insulation
• AC Voltage or Current
• Ground reference

PRELIMINARY INSTRUCTION

CAUTION

• The accessory can be used for RESISTANCE measurements on installations with CAT III 300V to ground
• Do not use the accessory on loads with technical specifications different by the same described in § 7. We invite you to follow the normal safety rules aimed at protecting against dangerous voltages and protecting the accessory against incorrect use
• Check that the rated operating voltage value indicated on the back label should be consistent with the power supply voltage of the system under test
• Do not use the accessory in circuits with voltages and currents higher than the rated ones
• Do not carry out any measurement in case you find anomalies in the accessory such as deformation, breaks, substance leaks, absence of display on the screen, etc.

DURING USE
Please carefully read the following recommendations and instructions:

CAUTION
The Failure to observe the warnings and/or instructions may damage the accessory and/or its components or be a source of danger for the operator

• Before changing function, disconnect the test leads from the circuit under test
• When the accessory is connected to the circuit under test, never touch any terminal, even if unused
• Avoid measuring resistance if external voltages are present. Even if the accessory is protected, excessive voltage could cause damage

DEFINITION OF MEASUREMENT (OVERVOLTAGE) CATEGORY
Standard “IEC/EN61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements” defines what measurement category, commonly called overvoltage category, is. § 6.7.4: Measured circuits, reads: circuits are divided into the following measurement categories:

• Measurement category IV is for measurements performed at the source of a low-voltage installation.
  Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.

• Measurement category III is for measurements performed on installations inside buildings.
  Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation.

• Measurement category II is for measurements performed on circuits directly connected to the low-voltage installation.
  Examples are measurements on household appliances, portable tools and similar equipment.

• Measurement category I is for measurements performed on circuits not directly connected to MAINS.
  Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that reason, the standard requires that the transient withstand capability of the equipment is made known to the user

OPERATING INSTRUCTIONS

CONTINUITY MEASUREMENT OF PROTECTIVE CONDUCTORS WITH 10A

CAUTION

• The power supply voltage of the accessory must be: 230/240V ± 10% (207V ÷ 265V) or 110V ± 10% (100V ÷ 120V). Do not use external power supply voltages external from the above ranges to avoid damaging the instrument
• Check that the rated operating voltage value indicated on the back label should be consistent with the power supply voltage of the system under test

1. Connect the accessory to the power supply using the supplied network cable (see Fig. 1 – part 10). The POWER LED is steady green to identify the correct power supply voltage, the STATUS LED is steady green to identify the operation of the accessory in Manual mode (see user manual of the MASTER instrument) and the WiFi LED is on in green flashing color to identify that the accessory is trying to make (if available) a WiFi connection with an external mobile device via the HTAnalysis APP (refer to the HTAnalysis instructions for managing the operation)
2. Connect the accessory to the MASTER instrument (see Fig. 3) by using the C2050 cable supplied (see Fig. 1 – part 1)
