SAFETY WARNINGS

Carefully read this user‘s manual before first using the device and keep it with the product so that a user can become acquainted with it. Prevent this user‘s manual from being destroyed.

• Check the device for damage before using it. Check that device‘s plastic cover is not damaged, that the insulation on the measuring probes is not damaged, that the display is not cracked, etc. Do not use the device if it is damaged and have this condition repaired.
• For measuring voltage within the permitted range, the original test probes supplied with the device must be used.
• The measuring device must not be used for measuring voltage/current exceeding the permitted values.
• Do not touch the uninsulated metal parts of the measuring probes while performing measurements. Hold the probes by the insulated grips.
• Do not use the device in an environment where there is a fire or explosion hazard or in a humid or wet environment. Keep your hands perfectly dry when performing measurements.
• Prior to changing the measured parameter, disconnect the test probes from the measured circuit.

WARNING

• For safety reasons, do not use the CAT III overvoltage category measuring device to measure electrical installations requiring a level IV overvoltage category (CAT IV). The specifications for the individual overvoltage categories CAT I to CAT IV according to EN 61010-1 are provided below and are illustrated in the following picture.

• Electrical installations requiring an overvoltage category IV (CAT IV) measuring device are the following:
  Electrical equipment located in the near vicinity of a building‘s power source, between the input into the building (junc-tion box) and the main switchboard. Such equipment may include, for example, tariff electricity meters and primary overvoltage protection devices.

• Electrical installations requiring an overvoltage category III (CAT III) measuring device are the following:
  Equipment that is part of the electrical installation in a building. Such equipment includes power sockets, circuit breaker boards and certain other mains power control installations. The measuring device meets the requirements for the CAT III protection level only up to the specified voltage value; and it must not be used for measuring installations requiring the CAT III level which are at higher voltages.

• Overvoltage category II (CAT II) includes equipment intended to be powered from the building installations. This applies both for equipment connected to power sockets as well as for permanently connected equipment.

• Overvoltage category I (CAT I) covers equipment intended for connection to mains power, where the equipment incorporates measures that significantly and reliably reduce transitional overvoltage to a level that cannot present a hazard. Overvoltage category I (CAT I) is not relevant to norm EN 61010-1, according to which the measuring device has been tested.

• A measuring device with a higher overvoltage category (CAT) can be used to measure installations belonging to a lower overvoltage category, e.g. a multimeter with CAT III protection for the defined voltage can be used to measure CAT II installations in the permitted voltage range, however, a CAT III multimeter cannot be used for measuring installations belonging in category CAT IV.

WARNING

• The device must be used for measuring using measuring probes intended only for the given CAT overvoltage category with the specified maximum voltage for the given voltage cate-gory, i.e. measuring probes with a specified CAT III for the specified voltage cannot be used for measurements on CAT IV installations.

Maintenance

• Please do not attempt to open the bottom cover for performing adjustments or repairs to this device. Such operations may only be performed by qualified persons that are fully acquainted with this device and that know the risks of injury by electrical shock.
• Prior to opening the case of the device or before removing the battery compartment cover, the probes of the measuring device must be removed from the measured circuit.
• y As soon as the symbol “ ” appears on the display, the batteries must be replaced immediate-ly to prevent injury by electrical shock that could result from erroneous measurement readings.
• When cleaning the device, use a damp cloth and a detergent solution, however, prevent water from entering the device. Do not use abrasive cleaning products or solvents.
• When this device is not being used, turn it off, turn the selection dial to position OFF.
• When this device is not used for an extended period of time, take out its batteries to prevent it from being damaged.

PROCEDURE FOR CALCULATING MEASUREMENT ACCURACY
The alternating voltage value is shown on the display, e.g. 180.1 V.
According to the table, for the range ≤ 600 V AC the specified accuracy is: ± (0.8% of value +5 digits).

Measurement accuracy is calculated as follows:

1. Calculate the uncertainty range: ±0.8% from 180.1 V; the uncertainty range is: 178.6-181.5 V.
2. To the decimal value then add the number „5“, the measured voltage is in the range: 179.1-182 V.

THE TEMPERATURE CORRECTION COEFFICIENT FOR CALCULATING ACCURACY AT <18 °C OR >28 °C IS: 0.1
At a measurement temperature of <18 °C or > 28 °C, the calculation procedure is the same as above, however, 0.1 is added to X%, accuracy is then expressed according to ± (0.9% of the value +5 digits).

Operating Instructions

HOLDING VALUES ON THE DISPLAY

If there is a requirement to hold the values on the display during the measurement process, gently press button and the displayed value will be held. To cancel the values held on the display, again gently press button .

DISPLAY BACKLIGHT

1. If ambient light is too weak during the measuring process, thus causing difficulties in reading off values, then hold down button for longer than 2 seconds and the display backlight will turn on, which will automatically turn off after approximately 1 minute.
2. If button is held down for longer than 2 seconds during this process, the display backlight will turn off.

AUTOMATIC SHUT-OFF

1. After approximately 10 minutes of inactivity, the device will turn off automatically. The buzzer will beep before the device turns off to inform you that it is turned off.
2. After an automatic shut-off, press any button to activate the device to the operating state.
3. When turning on the measuring device, simultaneously hold down the SEL/NCV button to cancel the automatic shut-off function.

NON-CONTACT DETECTION OF VOLTAGE (NCV)

1. Hold down the NCV button for 2 seconds (fig. 1, position 6) to activate the NCV function and the display will show the picture below (it does not matter whether the selection dial is set to the voltage or current measurement mode).
   

2. Press the NCV button (fig. 1, position 6) and place the NCV sensor in the vicinity of the measured cable. The device may detect when the alternating-current voltage in the measured cable is greater than 90 V. When the device detects alternating-current voltage, the built-in buzzer will start a warning and the display backlight will flash (fig. 3).
   

ATTENTION

• NCV detection is only indicative, and detection is dependent on shielding by the environment. If the device does not detect voltage with the NCV method, it does not necessarily mean that there is no live conductor under voltage or that there is no life threatening voltage inside the conductor in the tested location (e.g. inside a wall).

ATTENTION

• In this measurement mode, the voltage value will not be shown on the display.

ATTENTION

• In the NCV detection mode, the device will simultaneously measured voltage, resistance and current.

NON-CONTACT MEASUREMENT A~

WARNINGS

• Do not measure a current the value of which exceeds the limit value spe-cified in the technical specifications.
• Do not touch the measured circuit during measurement.
• The measurement of current higher than 200 µA must be performed in a non-contact manner using the clamp.

Turn the selection dial to position A Hz, open the clamp and insert the L-phase conductor into the clamp. The primary LCD display of the device will show the measured current value, the secondary LCD display will show the frequency of the current (fig. 4).

ATTENTION

• The flowing current can only be measured on an L-phase conductor. In the event that a cable that includes, in addition to the “L” phase also a “N” conductor, e.g. a television power cord, the measurement will not work.

NON-CONTACT MEASUREMENT A~

WARNINGS

• Do not measure a current the value of which exceeds the limit value spe-cified in the technical specifications.
