Safe working habits

To avoid possible electric shock or personal injury,and to avoid damage to the instrument or the object to be measured, use the meter in the following ways:

• Inspect the instrument. Do not use the instrument if the case is damaged. Check for cracks or missing plastic parts.Pay particular attention to the insulating layer of the connector.
• Inspect the test leads for insulation damage or bare metal. Check the continuity of the test leads. If the test leads are damaged, replace them before using the instrument.
• Use the instrument to measure a known voltage to make sure the instrument operates normally.
• Do not use if the instrument is working abnormally. Protection facilities may have been damaged. If in doubt, the instrument should be sent for maintenance. Do not apply any voltage beyond the rated voltage indicated on the meter between any terminal and earth ground.
• Warning: When working above 30Vuse caution not to touch exposed contacts due to risk of electric shock. Only use the approved probes or clamps.
• Measurements must be made with the correct jack, function and range. .
• Do not use the instrument near explosive gases, vapours or dust.
• When using the test leads, keep your fingers behind the test lead protector.·
• When connecting,first connect the common test lead, and then connect the live test lead. When disconnect, the live test lead and then disconnect the common test lead.
• Before you test the resistance,continuity and diodes, you must first cut off the power, and discharge all the capacitors.
• If the meter is not used in accordance with the instructions, the safety protection provided by the instrument may be impaired or invalidated.
• Ensure the instrument is switched off when opening the battery cover.
• When the battery under voltage indicator "ea"lights up, immediately replace the battery. When the battery power is low, the meter may produce incorrect readings, resulting in electric shock and personal injury. DO NOT mix new and old batteries and do not use re-chargeable batteries.
• Before opening the battery cover, the test leads must be removed from the instrument.
• Please use a soft cloth to clean instrument case, do not use abrasives or solvents.
