SAFETY PRECAUTIONS AND PROCEDURES

This instrument has been designed in compliance with IEC/EN61010-1 directive. For your own safety and to avoid damaging the instrument we suggest you follow the procedures hereby prescribed and read carefully all the notes preceded by the symbol .

CAUTION
Should you fail to keep to the prescribed instructions you could damage the instrument and/or its components or endanger your safety.

Take extreme care of the following conditions while taking measurements:

• Do not use the instrument in presence of explosive gas (material), combustible gas (material), steam, or dust.
• Do not touch the circuit under test even though you are not taking measurements.
• 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 below symbols are used:

| Caution: Refer to the instruction manual; improper use may damage the instrument or its components
---|---
| Dangerous high voltage: risk of electrical shocks
**| Double insulated instrument
` ~**`| AC voltage and current

1.1 PRELIMINARY INSTRUCTIONS

• It can be used for VOLTAGE measurements up to 600V AC on installations with overvoltage category CAT III 600V~ between inputs and 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 safety precautions before taking action on the plant.
• Do not perform any test under environmental conditions exceeding the limits indicated in this manual (see § 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 under good conditions and must be replaced, if
  necessary, with identical models.

1.2 DURING USE
Carefully read the below recommendations and instructions:

CAUTION

• No compliance 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.

1.3 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 § 9.2.

1.4 OVERVOLTAGE CATEGORIES – DEFINITIONS
IEC/EN61010-1 (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 § 6.7.4: Measuring circuits you read:
(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 instruments 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 a 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 withstanding capability of the equipment is made known to the user.

GENERAL DESCRIPTION

2.1 INTRODUCTION
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 the ground.

2.2 FUNCTIONS
This manual is referred to two models: XL423 and XL423. Where not expressly indicated the characteristics are common for both models. XL423 can record a single voltage in a single-phase or three-phase plant. XL424 can record up to 3 voltages simultaneously in a single-phase or three-phase plant.
The instrument can monitor a plant for a long time thanks to sophisticated memory managing algorithms. More exactly, the instrument uses the following sampling periods:

Measuring Interval| XL423 – Autonomy (days)| XL424 – Autonomy (days)
---|---|---
1s| 5| 2.
6s| 34| 8
The 30s| 170| 42
1min| 364 ()| 91
5min| 1820 ()| 455 (*)

(*) Depending on the batteries’ autonomy

The instrument starts each recording using the Measuring Interval set through PC management software (see § 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 storing data according to the new sampling period.

PREPARATION FOR USE

3.1 PRELIMINARY CHECKS
This instrument has been checked mechanically and electrically before shipment. All precautions have been taken to assure that the instrument reaches you under perfect
conditions. However, it is advisable to carry out a rapid check in order to detect any possible damage, which might have occurred during transport. Check the accessories
contained in the packaging to make sure they are the same as reported in § 11.

3.2 POWER SUPPLY
The instrument is powered by 2×1.5V type AA LR06 alkaline batteries. For battery replacement please follow the procedure described in § 9.2.

CAUTION

• After replacing batteries the instrument remains ON also if STATUS and ALARM LED are OFF. Pressing the START/STOP key you activate or disable recordings only.
• During a recording, the blinking ALARM LED every 3 seconds means a low battery status.

3.3 STORAGE
In order to guarantee the accuracy of measurements, after a period of storage under extreme environmental conditions wait until the instrument stabilizes within the listed
operating conditions (see § 10.2).

MAINTENANCE

9.1 GENERAL INFORMATION
This instrument is a precision instrument. Whether in use or in storage, please do not exceed the specifications to avoid any possible damage or danger during use. Do not
place this instrument under high temperature and/or humidity or expose it to direct sunlight.
For long-term storing, remove the batteries to avoid leakage of battery fluid that can damage the internal components.

9.2 BATTERY REPLACEMENT
Blinking the ALARM LED for 3 seconds means that the batteries are low. Stop the recording and replace the batteries with a new set. The management software allows the
operator to verify the battery’s status.

CAUTION
The instrument could keep the data stored even without batteries. The set date and time don’t get lost provided that the battery replacement takes less than 2 minutes.

CAUTION
Only experts and trained technicians should perform this operation. Remove the flexible head from the conductor under test before replacing the batteries.

1. Stop the recording (if necessary), remove the flexible heads from the conductors under test and transfer the stored data to a PC.
2. Remove the covers on the bottom side of the instrument using a screwdriver in the proper positions (1) and unscrew the 4 fixing screws (see Fig. 5).
3.  Open the box and unscrew the cover’s fixing screw of the battery housing.
4. Replace the batteries with a new set of the same type (see § 10.1.2). Close the battery housing with the screw, reinsert the screws, screw them and reinsert the plastic covers.
5. Do not throw flat batteries in the environment after use.

9.3 CLEANING
