The BT-6688B is a high-performance digital megohmmeter designed for measuring insulation resistance, AC voltage, and frequency. It features a wide testing voltage range and a protective casing per durevolezza.
2. Informazioni sulla sicurezza
Always adhere to safety precautions when using this device. Failure to do so may result in electric shock, injury, or damage to the meter. This device complies with IEC-1010 double insulation and overvoltage category II safety standards.
- Prima dell'uso, assicurarsi che il misuratore sia in buone condizioni di funzionamento.
- Do not operate the meter if the casing is damaged or if any part is exposed.
- Always use the correct test leads and accessories provided with the meter.
- Avoid touching the test leads or circuits during measurement, especially when high voltage è presente.
- During any rated voltage measurement, if the measured resistance is less than 5 MΩ, the measurement time should not exceed 10 seconds.
- The meter generates high voltage during insulation resistance tests. Exercise extreme caution.
- Non utilizzare il misuratore in ambienti umidi o in presenza di gas o polveri esplosive.
- Fare riferimento ai codici e alle normative locali sulla sicurezza elettrica.

6. Istruzioni per l'uso
6.1 Volume ACtage Misurazione
Il BT-6688B può misurare la tensione alternatatage from 1V to 750V with a frequency range of 40Hz to 400Hz.
- Assicurarsi che il misuratore sia SPENTO.
- Insert the red test lead into the "V~" terminal and the black test lead into the "COM" terminal.
- Turn the rotating switch to the "750V~" position.
- Carefully connect the test probes to the circuit or device where AC voltage deve essere misurato.
- Leggi l'AC voltagIl valore visualizzato sul display LCD.

6.2 Misurazione della resistenza di isolamento
The BT-6688B measures insulation resistance from 0.1 MΩ to 200 GΩ with selectable test voltages.
- Ensure the meter is OFF and the circuit under test is de-energized.
- Insert the red test lead into the "L" terminal and the black test lead (with the large clip) into the "E" terminal.
- Clamp the large test clip to one end of the object to be tested (e.g., ground or neutral).
- Select the desired insulation test voltage (100V, 250V, 500V, 1000V, 2500V, or 5000V) using the rotating switch.
- Connect the red test probe to the other end of the object to be tested (e.g., live conductor).
- Press the "TEST/STOP" button to initiate the test. The "HV" indicator will light up, indicating high voltage uscita.
- Read the insulation resistance value displayed on the LCD.
- Press "TEST/STOP" again to stop the test and discharge the circuit.
