6 Preparations
◼ Operating precautions
Safe use for the calibrator
⚫ When using the calibrator for the first time, be sure to read the safety information listed in Section IV.
⚫ Do not open the instrument housing.
To inspect or repair the instrument’s internal components, please contact the seller from whom you purchased the product.
⚫ Malfunctioning conditions
If the instrument starts to release fume and emit a strange smell, or other abnormal phenomena occur, immediately turn off the
instrument and remove the batteries. Then contact the seller from whom you purchased the instrument.
◼ General operations
⚫ Before moving the calibrator, turn off the power of the tested instrument and then the power of the calibrator. Finally, unplug all test
leads from the calibrator. Use a professional transport packaging box when transporting the calibrator.
⚫ Do not allow any live objects to approach the calibrator in case its internal circuitry gets damaged.
⚫ Do not apply any volatile chemicals to the calibrator housing and operator panel, and do not leave the calibrator attached to any object
made of rubber or vinyl for too long. Take care to prevent the operating panel, which is made of thermoplastic resin, from contacting
soldering iron, soldering tin or heating objects.
⚫ For safe operations of battery, please refer to the “Install or replace batteries” section.
⚫ Do not use the calibrator without the battery cover installed.
◼ Environmental requirements
Use the instrument under the environmental requirements listed below:
⚫ Ambient temperature and humidity
Ambient temperature: 0-50℃
9
Ambient humidity: 20%-80%; use the instrument under non-condensing conditions
⚫ Use the instrument in a flat and horizontal area
◼ Do not use the instrument in the following environment
⚫ Places directly exposed to sunlight or close to heat sources
⚫ Places close to mechanical vibrations

Note:
⚫ If precise measurements or output results are required, use the calibrator under the following environmental requirements:
Ambient temperature range: 23±5℃; ambient humidity range: 20-80% (without condensation)
When using the calibrator in an environment of 0-18℃ or 28-50℃, refer to the Index section and add an additional error value at this
temperature coefficient to achieve the given accuracy.
⚫ When the humidity of the surrounding environment where the instrument is located is less than 30%, use an anti-static pad or take other
effective measures to prevent the generation of static electricity.
⚫ If the instrument needs to be moved from a place with lower ambient temperature or humidity to a place with higher ambient
temperature, or if the instrument is to undergo a sudden temperature change, warm up the instrument for at least one hour under the
ambient temperature before using to ensure its proper operation.
◼ Install or replace batteries
10
WARNING
⚫ To avoid electric shock, the test lead must be removed from the calibrator before opening the battery door. The battery door must be
closed tightly before using the calibrator.
Caution
⚫ To prevent the risk of liquid leakage or battery explosion, install the positive and negative poles of the battery correctly.
⚫ Do not short-circuit the battery.
⚫ Do not disassemble or heat the battery, or throw the battery
into a fire.
⚫ When replacing batteries, use 3 identical batteries to replace them
simultaneously.
