HT6-HT8-HT9 1. PRECAUTIONS AND SAFETY MEASURES The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to electronic measuring instruments. For your safety and in order to prevent damaging the instrument, please carefully follow the procedures described in this manual and read all notes preceded by the symbol with the utmost attention.
HT6-HT8-HT9 1.2. DURING USE Please carefully read the following recommendations and instructions: WARNING Failure to comply with the caution notes and/or instructions may damage the instrument and/or its components or be a source of danger for the operator. When the instrument is connected to the circuit being tested, do not touch any unused terminal. Avoid measuring continuity if external voltages are present. 1.3. AFTER USE If the instrument is not to be used for a long time, remove the batteries.
HT6-HT8-HT9 2. GENERAL DESCRIPTION This manual refers to the following products: HT6, HT8, HT9.

HT6-HT8-HT9 4.2. AUTO POWER ON MODE / SWITCHING ON The instruments switch on in the following cases: if continuity is detected; if an AC or DC voltage higher than 10V is detected; if a live phase is connected to lead L2; of the Torch button is pressed; if the ON/Reset button is pressed (on models HT6 and HT8); if the Lamp test button is pressed (on model HT9) 4.3.
HT6-HT8-HT9 5. INSTRUMENT FUNCTIONS 5.1. VOLTAGE MEASUREMENT AND POLARITY INDICATION WARNING The maximum input AC and DC voltage is 690V. Do not measure voltages exceeding the limits given in this manual. Exceeding these limits could result in electrical shocks to the user and damage to the instrument. The Dangerous voltage led (see Fig. 2 – no.
HT6-HT8-HT9 5.2. PHASE DETECTION FUNCTION WITH 1 TERMINAL WARNING The maximum input AC and DC voltage is 690V. Do not measure voltages exceeding the limits given in this manual. Exceeding these limits could result in electrical shocks to the user and damage to the instrument. The quality of the indication cannot be reliable if you work under unfavourable conditions such as, for example, on wooden ladders, in rooms with insulated floors, etc.
HT6-HT8-HT9 5.3. PHASE SEQUENCE WARNING The maximum input AC and DC voltage is 690V. Do not measure voltages exceeding the limits given in this manual. Exceeding these limits could result in electrical shocks to the user and damage to the instrument. Correct indication is only guaranteed for AC voltage in a range between 100V and 690V and with a frequency between 50Hz and 60Hz on threephase 4-wire electrical systems.
HT6-HT8-HT9 5.4. CONTINUITY TEST WARNING Before carrying out any continuity test, check that the resistance to be measured is not live. Failure to respect this prescription may seriously harm the operator. 1. Connect the measuring leads L1 and L2 to the object to be tested (see Fig. 6). 2. The instrument switches on automatically together with led RX (see Fig. 2 – no. 6) and the buzzer sounds continuously in case the result of the continuity test is positive. 3.
HT6-HT8-HT9 5.5. LAMP TEST WARNING During the test, do not touch the socket of the lamp, as you may obtain unreliable results. During the test, do not touch the test lead, as a high test voltage is present. During the test with the test lead, do not touch any other object than the lamp being tested.
HT6-HT8-HT9 Mercury-vapour lamp and halogen lamp test Touch the glass of the tube or a supply pole with the lead and press the “Test” button. If lighting is not steady, the tube is defective. If the tube only operates when it is not installed and turns off and on or seems unsteady when it is installed, check that the tube is not unusually overheated, as this may cause a repeated opening and closing of the tube switch. 6.
