VM-3024S/H Instruction Manual
(Compatible with Version 2.16 or later)
8. Troubleshooting
(1) In case of over range
When the over range icon
appeared during use, modify the range setting as
explained in Fig.3-5. Over range will be adjusted automatically in the auto range setting.
If the over range icon
is frequently lit in Auto Range “ON”, use manual range
(Auto Range is set “OFF”).
(2) The screen is not displayed
The following causes are considered. Check the following (A) to (D).
(A) Battery voltage is below 2.0V.
(B) Polarity of the battery is wrong.
(C) Pickup cable is not properly connected to the equipment.
(D) AC adaptor is broken (if AC adapter is used), or not properly connected to the
equipment.
When no problem was found in the 4 items above, (A) to (D), turn off and restart the
machine.
(3) AC output and DC output waveforms are greatly disturbed
If “Auto Range” is set to “ON”, the vibration value fluctuates greatly immediately after
when the measurement range switched. At this time, AC output and DC output fluctuate
greatly, and correct measurement results cannot be obtained.
When performing measurement using AC output and DC output, be sure to set
“Auto Range” to “OFF”.
9. Precautions
(1) Turn off and remove batteries when not in use for long period of time.
(2) Avoid high temperature or humidity to protect LCD screen. Store the equipment in dry
place under 35°C. Do not leave the machine under direct sunlight or in a car.
(3) Keep the machine away from organic solvent like ketone or thinner to protect the body
made of ABS resin.
For cleaning, use soft clothes. You may use a small amount of
alcohol.
(4) Avoid strong shock. The screen is made of glass.
(5) Do not disassemble the equipment. You can open only the battery box cover.
(6) When disposing of the product, please dispose of it as industrial waste.
