Please don’t importing the voltage in the temperature function.
3.9 Diode test
1) Connect the black test lead to "COM" socket and red test lead to the " VΩ"
socket.
2) Set the selector switch to " " position.
3) Push "SELECT" to select diode test.
4) Connect the black and red test probe to the cathode (-) and anode (+)
ends of diode to be tested respectively, read the forward voltage drop
(junction) value from the display. If reverse connected the probes to
diode, display shows over-load.
Caution: Ensure that the circuit to be tested is "dead".
Max. input over-load: 250V rms＜10sec
3.10 Audible continuity test
1) Connect the black test lead to "COM" socket and red test lead to the "VΩ"
socket.
2) Set the selector switch to " " position.
3) Push "SELECT" to select audible continuity test.
4) Connect the probes across circuit to be tested, the beeper sounds
continuously if the resistance is less than approx. 90Ω.
Caution: Ensure that the circuit to be tested is "dead".
Max .input over-load: 250V rms＜10sec
3.11 Relative measurement
Press "REL", you can measure the relative value and "REL" appears on the
display, the auto range mode be changed to manual range mode. Press
again, return to the previous condition and "REL" disappears, but you
can not go back to auto range mode. In” Hz” measurement, you can
not measure the relative value.
4. CARE AND MAINTENANCE
4.1 CARING FOR YOUR MULTIMETER
AP-570CAPP clamp meter is a product of superior design and craftsmanship.
The following suggestions will help you care for the multimeter so you can
enjoy it for years.
1) Keep the multimeter dry. If your multimeter gets wet, please wipe it dry
immediately. Liquids possibly contains minerals which would corrode
electronic circuits.
2) Please use and store the multimeter only in normal temperature environments.
Extreme temperature would shorten the life of electronic devices, damage
batteries and distort or melt plastic parts.
3) Please handle the multimeter gently and carefully. Dropping it would
damage the circuit boards which leads to the multimeter would work
improperly.
4) When taking current measurement, please keep the cable in the middle of
the clamp jaws for getting more accurate test result.
