2. सुरक्षितता माहिती

Always observe the following safety precautions when using the multimeter:

• दुहेरी इन्सुलेशन: The multimeter features double insulation for user protection. Do not attempt to bypass or modify this safety feature.
• मापन श्रेणी: This device is rated CAT III 300V and CAT II 500V. Ensure that the measurement category and voltage rating are appropriate for the circuit being tested.
• Inspect Test Leads: Before each use, inspect the test leads for any damage to the insulation or exposed metal. Do not use damaged leads.
• Do Not Exceed Maximum Input Values: Refer to the specifications section for maximum input values for each function. Exceeding these limits can damage the meter and pose a safety risk.
• फ्यूज संरक्षण: The multimeter is protected by fuses (500mA 500V Fastrapid and 10A 500V Fastrapid). If a fuse blows, replace it only with a fuse of the specified type and rating.
• बॅटरी पातळी: Ensure batteries are adequately charged. A low battery indicator may affect measurement accuracy.
• पर्यावरणीय परिस्थिती: Operate the multimeter within the specified operating temperature range (0°C to +40°C).
• योग्य कनेक्शन: Always connect the common (COM) test lead first, then the live test lead. Disconnect the live test lead first, then the common test lead.
• ओले वातावरण टाळा: Do not use the multimeter in wet or damp वातावरण
