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.
