TECHNO VIETNAM KEW 1061 Digital Multimeters

Product Information

The KEW 1061/1062 Digital Multimeter is a measuring tool that uses modulation for A/D conversion, allowing for fast and accurate measurements. It has a 5-digit LCD display with a maximum reading of 50000 and a bar graph indicator. The multimeter has switching detection modes for effective value (root mean square value) detection (RMS) and mean value detection (MEAN) during AC voltage or AC current measurement (KEW1062 only). Additionally, it has a low- pass filter that can be switched on/off during AC voltage or AC current measurement (KEW1062 only). The multimeter complies with CE standards and features a current-input terminal shutter for preventing wrong input. It uses high-performance UL-standard fuses.

4. Operation
4.1 Precautions Before Measurement
n Examining Items Contained in the Package After opening the package, be sure to examine the product as instructed below before use. Should the delivered product be the wrong model, lack any item, or show any flaw in its appearance, contact the vendor from which you purchased the product.
n Precautions of Operation and Storage
CAUTION
· Insert the batteries in the instrument by referring to “6.1 Battery Replacement.” · A Blank cover is provided on the upper part of back casing.
Don’t remove the Blank cover except when the USB adapter or Printer adapter is connected. · Do not use the instrument near noise-emitting equipment or where there may be a sudden change of temperature. Otherwise, the instrument may give an unstable reading or errors. Removal of Dirt Do not wipe the instrument using any solvent (chemicals) such as benzine or paint thinner, as this may damage or discolor the front panel. Use a dry cloth to clean the instrument. Storage Conditions · Do not leave the instrument exposed to direct sunlight or in a hot and humid location such as the inside of a vehicle, for any prolonged length of time. · If the instrument will not be used for a prolonged period, remove the batteries.
