Manwal tal-Utent tal-Multimetru DigiTech Cat III bit-Temperatura

Introduzzjoni

This user manual provides essential information for the safe and effective operation of your DigiTech Cat III Multimeter with Temperature, model QM1323. Please read this manual thoroughly before use and retain it for future reference.

The DigiTech QM1323 is a compact, battery-powered multimeter designed for various electrical measurements, including voltage, current, resistance, frequency, capacitance, and temperature. It is rated for CAT III applications, ensuring safety for measurements in building installations.

Informazzjoni dwar is-Sigurtà

Always adhere to the following safety precautions to prevent personal injury or damage to the multimeter:

• Teċċedix il-limiti massimi tad-dħul għal kwalunkwe funzjoni.
• Oqgħod attent meta taħdem bil-voltag'il fuq minn 30V AC RMS, 42V peak, jew 60V DC. Dawn il-volumitages joħolqu periklu ta' xokk.
• Ensure the test leads are in good condition and properly seated in the input jacks.
• Do not operate the multimeter if it appears damaged or if the case is open.
• Always turn off power to the circuit under test before connecting or disconnecting test leads for current measurements.
• Ibdel il-batterija meta jidher l-indikatur ta' batterija baxxa biex tiżgura qari preċiż.

Komponenti Ewlenin:

• Display LCD: Juri l-qari tal-kejl, l-unitajiet, u l-indikaturi tal-funzjoni.
• Dial tal-Funzjoni: Used to select the desired measurement function (e.g., V, A, Ω, Hz, Temp).
• Ġakkijiet tad-dħul:
  • COM Jack: Input komuni (negattiv) għall-kejl kollu.
  • VΩTemp Jack: Input pożittiv għall-volumtagKejl tar-reżistenza, tal-frekwenza, tal-kapaċitanza, u tat-temperatura.
  • mAµA Jack: Input pożittiv għal milliampere u mikroampkejl tal-kurrent ere.
  • 10A Jack: Positive input for 10 Ampere current measurements (fused).
• Buttuni tal-Funzjoni:
  • MODALITÀ: Toggles between different measurement modes within a function (e.g., AC/DC voltage, reżistenza/kontinwità).
  • FIRXA: Manually selects the measurement range.
  • ŻOMM: Jiffriża l-qari attwali tal-wiri.
  • REL (Relative): Measures the difference between a stored value and the current reading.

Setup

Installazzjoni tal-batterija:

The DigiTech QM1323 requires one 9V battery (included). To install or replace the battery:

1. Kun żgur li l-multimetru huwa MITFI.
2. Locate the battery compartment on the rear of the unit.
3. Ħoll il-vit(i) taż-żamma u neħħi l-għatu tal-batterija.
4. Connect the 9V battery to the battery clip, observing correct polarity.
5. Place the battery into the compartment and replace the cover, securing it with the screw(s).

Konnessjoni tal-wajers tat-test:

Dejjem qabbad il-wajer tat-test iswed mal- COM jack. Connect the red test lead to the appropriate input jack based on the measurement type:

• VΩTemp: Għal voltage, resistance, continuity, diode, capacitance, frequency, and temperature measurements.
• mAµA: Għal kejl tal-kurrent sa 400mA.
• 10A: Għal kejl tal-kurrent sa 10A.

Istruzzjonijiet Operattivi

This section details how to perform common measurements with your multimeter.

Kejl DC Voltage:

1. Dawwar id-dial tal-funzjoni lejn il- V position. The display will show "DC".
2. Qabbad iċ - ċomb iswed tat - test mal - COM jack and the red test lead to the VΩTemp jack.
3. Connect the test leads in parallel across the DC voltage source or component to be measured.
4. Aqra l-voltage valur fuq il-wiri LCD.

Kejl AC Voltage:

1. Dawwar id-dial tal-funzjoni lejn il- V pożizzjoni.
2. Agħfas il- MODALITÀ button to toggle to "AC".
3. Qabbad iċ - ċomb iswed tat - test mal - COM jack and the red test lead to the VΩTemp jack.
4. Connect the test leads in parallel across the AC voltage source or component to be measured.
5. Aqra l-voltage valur fuq il-wiri LCD.

Reżistenza tal-Kejl:

1. Dawwar id-dial tal-funzjoni lejn il- Ω pożizzjoni.
2. Qabbad iċ - ċomb iswed tat - test mal - COM jack and the red test lead to the VΩTemp jack.
3. Ensure the circuit or component is de-energized before connecting the test leads.
4. Connect the test leads across the component whose resistance is to be measured.
5. Aqra l-valur tar-reżistenza fuq id-displej LCD.

Kejl tat-Temperatura:

1. Dawwar id-dial tal-funzjoni lejn il- Temp pożizzjoni.
2. Connect the temperature probe (if included) to the COM u VΩTemp ġakkijiet, josservaw il-polarità.
3. Place the tip of the temperature probe on or near the object whose temperature is to be measured.
4. Read the temperature value on the LCD display. The unit may be switchable between Celsius and Fahrenheit using the MODE button.

Manutenzjoni

Tindif:

Biex tnaddaf il-multimetru, imsaħ il-kaxxa b'adamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the unit is completely dry before use.

Sostituzzjoni tal-fjus:

If the current measurement function (10A or mAµA) stops working, the internal fuse may need replacement. Refer to the specifications for the correct fuse type and rating. Fuse replacement typically involves opening the back case of the multimeter. If unsure, consult a qualified technician.

Ħażna:

When not in use for extended periods, turn the multimeter OFF and remove the battery to prevent leakage. Store the multimeter in a cool, dry place, ideally in its protective case.
