support@hantek.com Safety Requirement General Safety Summary Be aware of the following safety precautions to avoid injury and prevent damage to the product or any product connected to this product. To avoid possible hazards, be sure to use this product in accordance with the regulations. Use the correct power cord. You are only allowed to use the specified power cord approved by the country you are currently in. Ground the product. This product is grounded through the protective grounding wire of the power cable. To avoid electric shock, please ensure that the grounding terminal of the

General Safety Summary

power cable is connected to the protective grounding terminal reliably before connecting to any input or output terminals of the product. View all terminal ratings. To avoid fire and excessive current shock, please check all the ratings and markings on the product and consult the product manual for details of the ratings before connecting the product. Use appropriate overvoltage protection. Ensure that no overvoltage (such as voltage caused by lightning) reaches to this product. Or else the operator may expose to danger of electric shock. Do not open the lid while operating. Do not operate the product with the machine case open. Use appropriate fuse. Only specified fuses are allowed.

Avoid exposed circuits. After powering on, do not touch exposed splices and components. Do not operate if the product is suspected to be out of order. If you suspect there is something wrong with the product, please contact maintenance personnel authorized by Hantek for testing. Any maintenance, adjustment or replacement of components must be performed by repairmen authorized by Hantek. Maintain good ventilation. Poor ventilation may cause the temperature of the instrument rising and then lead to damage to it. Good ventilation should be maintained when using, and the vents and fans should be checked regularly. Do not use in a humid environment.

To avoid short circuit and electric shock, do not operate the instrument in damp environment. Do not operate in a flammable and explosive environment. In order to avoid damage to the instrument or personal injury, do not operate the instrument in a flammable and explosive environment. Please keep the surface of the product clean and dry. To avoid dust and moisture in the air affecting the performance of the instrument, please keep the surface of the product clean and dry. Anti-static protection. Static electricity may cause damage to the instrument. It would be better to test the

instrument in anti-static area. Before connecting the cable to the instrument, the inner and outer conductors should be grounded briefly to release the static electricity. Pay attention to carrying safety. To avoid the instrument sliding in the process of carrying, causing damage to the keys on the panel, the knobs or interfaces, please pay attention to carrying safety. Interference tests for all models comply with Class A standards, based on EN 61326:1997 +A1+A2+A3 Input terminal protection limits. The protection limits are defined for the input terminals: 1. Main input (HI and LO) terminals.

The HI and LO input terminals are used for voltage, resistance, capacitance, connectivity, frequency, and diode test measurements. These two terminals define the following two protection limits: 1) HI to LO protection limit. The HI to LO protection limit is 1000 VDC or 750 VAC, which is also the maximum measurable voltage. This limit can also be expressed as a maximum of 1000 VPK. 2) Lo to the ground protection limit. LO input terminals can safely "float" to a maximum of 500 Vpk relative to the ground. The HI terminal protection limit is up to 1000 VPK relative to the ground. Therefore, the sum of the "floating" voltage and the measured voltage must not exceed 1000 VPK. 2. Sampling terminal.

1) The HI and LO Sense terminals are used for DCV proportional measurements, four-wire resistance and temperature measurements. The measurement limit for all terminal pairs is 200 Vpk: LO Sense to LO input, HI Sense to LO input, HI Sense to LO Sense. 3. Current input terminal. The measurement limit is 10.5A (DC or AC) when using the 10A-current- input terminal and the LO terminal. The measurement limit is 3.1A (DC or AC) when using 3A-current-input terminal and the LO terminal. Note: To avoid blowing the fuse or damaging the multimeter, please follow the instructions below to use the current input terminals.

1) When performing current test measurements, be sure to select an appropriate current input terminal according to the expected current size before switching on the multimeter power. 2) The maximum current input to 10A terminal shall not exceed 10.5A, otherwise, the
