Operating precautions

Safe use of 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 smoke, emits a strange smell, or shows other abnormal phenomena, 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 turn off the power of the calibrator. Finally, unplug all test leads from the calibrator. When transporting the calibrator, use a professional transport packaging box.
⚫ Do not allow any live objects to approach the calibrator in case its internal circuit gets damaged.
⚫ Do not use any volatile chemicals on 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 the soldering iron, soldering tin or heating objects.
⚫ For safe operations of the 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℃
- Ambient humidity : 20%-80%; use the instrument under non-condensing conditions
Use it 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
Approaching any interference source, such as high-voltage equipment or engine power
Approaching any electromagnetic field or high-density electric power area
Places filled with large amounts of oil fumes, heat flow, dust or corrosive gases
Unstable places or places with flammable gases that can cause an explosion

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℃, to achieve the given accuracy, refer to the Index section and add error value at this temperature coefficient.
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. In this case, warm up the instrument for at least one hour at the ambient temperature before using the instrument to ensure proper operation.

Install or replace batteries

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.
If the calibrator will not be used for an extended period of time, remove the batteries from the calibrator.

Figure 5

Step 1: Before replacing the battery, remove the test lead and turn off the calibrator.
Step 2 : Use a slotted screwdriver to rotate the battery door screw by a quarter turn counterclockwise and remove the battery door.
