2. Informació de seguretat
ADVERTIMENT: To ensure safe operation, always read, understand, and follow all instructions, cautions, and warnings provided with this kit and all test and measurement devices before each use. Failure to do so may result in serious injury or death.
- Do not attempt to measure resistance or continuity on live circuits.
- Abans de cada ús, verifiqueu el funcionament del comptador mesurant un volum coneguttage o actual.
- No utilitzeu el comptador durant tempestes elèctriques o en temps humit.
- No utilitzeu el mesurador ni els cables de prova si sembla que estan danyats.
- Always wear appropriate personal protective equipment (PPE) when working with electrical circuits.
- The CL110 Clamp Meter is rated for CAT III 600V. Ensure your application falls within these safety ratings.
3. Configuració
3.1 Battery Installation (CL110 Clamp metre)
The CL110 Clamp Meter requires three (3) AAA batteries (included). To install or replace batteries:
- Ensure the meter is turned OFF and disconnect all test leads from the meter and any circuit.
- Localitzeu la tapa del compartiment de la bateria a la part posterior del mesurador.
- Feu servir un tornavís per afluixar el cargol que fixa la tapa del compartiment de la bateria.
- Remove the cover and insert the AAA batteries, observing correct polarity (+/-).
- Torneu a col·locar la tapa del compartiment de la bateria i estrenyeu el cargol fermament.

3.2 Connecting Test Leads (CL110 Clamp metre)
Per al voltage, resistance, and continuity measurements, connect the included test leads to the meter:
- Inseriu el cable de prova negre al connector 'COM' (comú).
- Insert the red test lead into the 'VΩ' (voltage/resistance) jack.
- Ensure the leads are fully seated in the jacks before use.

4. Instruccions de funcionament
4.1 Using the CL110 400A Auto-Ranging Digital Clamp Mesurador
The CL110 is an auto-ranging meter, simplifying measurements by automatically selecting the correct range for most functions.
To Measure AC Current (via Clamp):
- Turn the rotary dial to the 'A~' (AC Current) setting.
- Obriu el clamp mandíbules prement el gallet.
- Encircle a single conductor (not a power cord with multiple conductors) with the clamp mandíbules. Assegureu-vos que les mandíbules estiguin completament tancades.
- Read the AC current value on the backlit display.

Per mesurar AC/DC Voltage, Resistance, or Continuity (via Test Leads):
- Connecteu els cables de prova tal com es descriu a la secció 3.2.
- Turn the rotary dial to the desired function: 'V~' for AC Voltage, 'V=' for DC Voltage, 'Ω' for Resistance, or '♫' for Continuity.
- Carefully touch the test probes to the circuit points you wish to measure.
- Read the measurement on the backlit display. For continuity, an audible tone indicates a continuous circuit.
4.2 Using the RT210 GFCI Receptacle Tester
The RT210 GFCI Receptacle Tester quickly identifies common wiring faults in 120V AC outlets.
- Plug the RT210 directly into the 120V AC receptacle.
- Observe the indicator lights on the tester. Refer to the legend on the tester for the meaning of different light patterns (e.g., Open Ground, Reverse Polarity, Correct Wiring).
- To test a GFCI receptacle, press the 'PUSH TO TEST GFCI' button. A working GFCI should trip, cutting power to the outlet. Reset the GFCI after testing.

4.3 Using the 69409 Line Splitter 10x
The 69409 Line Splitter allows for safe and convenient measurement of AC current draw for appliances up to 15A without needing to separate the conductors of a power cord.
- Plug the appliance's power cord into the Line Splitter.
- Plug the Line Splitter into a 120V AC wall outlet.
- Turn the CL110 Clamp Meter to the 'A~' (AC Current) setting.
- Clamp the CL110 around the '10x' loop on the Line Splitter. This loop amplifies the current by a factor of 10, providing a more precise reading for low current draws.
- Turn on the appliance and read the value on the CL110 display. Divide this reading by 10 to get the actual current draw of the appliance.
- For direct (1x) current measurement, clamp the CL110 around the '1x' loop.
5. Manteniment
5.1 Neteja
Wipe the meter and accessories with a clean, dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure the devices are dry before storage or use.
5.2 Battery Replacement (CL110 Clamp metre)
Replace the batteries when the low battery indicator appears on the display. Refer to Section 3.1 for battery installation instructions. Always use fresh AAA alkaline batteries.
5.3 Emmagatzematge
When not in use, store the kit components in the included carrying pouch in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries from the CL110 Clamp Meter to prevent leakage.
6. Solució De Problemes
- El mesurador no s'encén: Comproveu la instal·lació de les piles i assegureu-vos que les piles siguin noves.
- No reading or 'OL' (Overload) displayed: Ensure test leads are properly connected and the rotary dial is set to the correct function. For current measurements, ensure the clamp is fully closed around a single conductor. If 'OL' persists, the measured value may exceed the meter's range.
- Lectures inexactes: Verify meter operation with a known voltage or current source. Check for damaged test leads or dirty connections.
- GFCI Tester shows incorrect wiring: Consult a qualified electrician to inspect and correct the wiring of the receptacle.
- GFCI Tester does not trip GFCI: The GFCI receptacle may be faulty or improperly wired. Consult a qualified electrician.
