Take extreme care of the following conditions while taking measurements:

• Do not performing any measures in humid or wet environments.
• Do not use the meter in presence of explosive gas (material), combustible gas (material), steam or dust.
• Do not touch the circuit under test if no measurement is being taken.
• Do not use the instrument if it seems to be malfunctioning (i.e. if you notice deformations, breaks, leakage of substances and so on).

The herewith symbols are used:

• Caution: refer to the instruction manual; an improper use may damage the instrument or its components
• Danger high voltage: risk of electrical shocks
• Double insulated meter
• AC voltage and current

PRELIMINARY INSTRUCTIONS

• This instrument has been designed for use in environments of pollution degree 2 up to 2000m high.
• It can be used for VOLTAGE measurements up to 600V AC on installations with overvoltage category CAT III 600V~ between the inputs and to ground.
• Please use the standard safety precautions aimed at:
  • Protecting you against dangerous electric currents.
  • Protecting the instrument against incorrect operations.
• Do not test circuits exceeding the voltage limits.
• If possible de-energize the plant under test before connecting the instrument. Take all the safety precautions before taking actions on the plant.
• Do not perform any test under environmental conditions exceeding the limits indicated in this manual (ref. par. 10.2).
• Make sure that batteries are correctly installed.
• Only the accessories supplied with the instrument guarantee compliance with the safety standards. They must be in good condition and must be replaced, if necessary, with identical models.

DURING USE
Carefully read the herewith recommendations and instructions:

WARNING

• Noncompliance with warnings and/or instructions may cause damage to the tester or its components or injure the operator.
• During a measurement never touch any unused terminal.

AFTER USE

• If you expect not to use the instrument for a long period of time remove the batteries and strictly follow the indications at paragraph 9.2.

OVERVOLTAGE CATEGORIES – DEFINITIONS
EN 61010-1 (Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements) defines what a measurement category (usually called “overvoltage category”) is. At paragraph 6.7.4: Measuring circuits it says: (OMISSIONS)
Circuits are divided into the following measurement categories:

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

• Measurement category III is for measurements performed in the building installation.
  Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the 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 norm requires that the transient withstand capability of the equipment is made known to the user.

GENERAL DESCRIPTION

INTRODUCTION
Dear Customer, the instrument you have just purchased will grant you accurate and reliable measurements provided that it is used according to the present manual’s instructions. The instrument was designed to grant the user the utmost safety conditions thanks to a new concept assuring double insulation and overvoltage CAT III 600V~ between inputs and to ground.
FUNCTIONS
This manual is referred to two models: XL423 and XL423. XL423 can recording a single voltage in single phase or three phase plant. XL424 can recording up to 3 voltages simultaneously in single phase or three phase plant. Where not expressly indicated the characteristics are common for both models. The meter can monitoring a plant for a long time thanks to a sophisticated memorymanaging algorithm. More exactly, the instrument uses the following sampling periods:

Measuring Interval| XL423 – Autonomy (days)| XL424 – Autonomy (days)
---|---|---
1s| 5| 1.5
6s| 34| 8
30s| 170| 42
1min| 364 ()| 91
5min| 1820 ()| 455 (*)

The instrument starts each recording using the Measuring Interval set through PC DATALINK software (see chapter 8). Just before the event of full memory, the instrument applies the successive measuring Interval to all the memory, thus getting more free memory locations. The instrument continues the data storing according to the new sampling period.

PREPARATION FOR USE

PRELIMINARY CHECKS
This instrument has been checked mechanically and electrically before shipment. All precautions have been taken to assure that the instrument reaches you in perfect condition. However, it is advisable to carry out a rapid check in order to detect any possible damage,which might have occurred in transit. Check the accessories contained in the packaging to make sure they are the same as reported in chapter 11.
POWER SUPPLY
The instrument is powered by two 1.5V type LR6 AA AM3 MN1500 alkaline batteries. For battery life see paragraph 10.1.2. For battery fitting operation procedure please see paragraph 9.2.

WARNING

• The meter, after fitted batteries, is always continuously ON also if STATUS and ALARM LED are OFF. Pressing of START/STOP key activate or disable recordings only.
• During a recording the blinking ALARM LED every 3 seconds means a low battery status.

CALIBRATION
The instrument complies with the accuracy specifications listed in this manual and such compliance is guaranteed for 12 months, afterwards the tester may need recalibration.
STORAGE
In order to guarantee the accuracy of the measurements, after a period of storage in extreme environmental conditions wait for the instrument to stabilize to within the listed operating conditions (see paragraph 10.2).
