官网原文（英文）
• 官网产品概述（英文原文）：Two pole multifucntion tester with in-built LED torch · HT10 is designed to carry out the measurements of a digital tester in a practical, quick and functional way thanks to his narrow and long structure, which allows carrying out measurements in any operating conditions. This device carries out measurements of AC/DC voltage with polarity indication, continuity tests with buzzer and phase sequence detection with LED indications and display reading. HT10 carries out measurements of AC voltage with low input impedance and performs RCD trip testing (just trip testing, no time or current testing) as well. HT10 is also provided with a white LED torch for use in poorly lit environments, and complies with safety requirements of standards IEC/EN61243-3:2014/VDE 0682 ensuring safe and reliable working conditions. The instrument indicates whether a dangerous voltage is present, even if there is no…

附件 · all the notes preceded by the symbol ::
• CAUTION：• Depending on the internal impedance of the voltage detector there will be a different capability of indicating the presence or absence of operating voltage in case interference voltage is present • A voltage detector of relatively low internal impedance, compared to the reference value of 100kΩ, will not indicate all interference voltages having an original voltage value above the ELV level. When in contact with the parts to be tested, the voltage detector may temporarily discharge the interference voltage to a level below ELV, but voltage will be back to the original value when the voltage detector is removed • When the indication “voltage present” does not appear, it is highly recommended installing earthing equipment before proceeding • A voltage detector of relatively high internal impedance, compared to the reference value of 100kΩ, may not permit to clearly indicate the absence of operating voltage in case interference voltage is present • When the indication “voltage present” appears on a part that is expected to be disconnected from the installation, it is highly recommended confirming by other means (e.g. use of another voltage detector, visual check of the disconnected parts of the electric circuit to be tested, etc.) that there is no operating voltage on the part to be tested and to conclude that the voltage indicated by the voltage detector is an interference voltage • A voltage detector declaring two values of internal impedance has passed a performance test of detecting interference voltages and is (within technical limits) able to distinguish operating voltage from interference voltage and has a means to directly or indirectly indicate which type of voltage is present • This instrument has been designed for use in environments with pollution degree 2. • It can be used for DC and AC VOLTAGE measurements on installations of CAT IV 600V or CAT III 1000V
