HT9019 1. SAFETY PRECAUTIONS AND PROCEDURES This clamp complies with IEC/EN61010-1. For your own safety and in order to avoid damaging the instrument, you’re recommended to keep to the instructions contained in this manual and read carefully all the notes preceded by the symbol . Take extreme care for the following conditions while measuring: Do not measure voltage or current in humid or wet environment.
HT9019 1.2. DURING USE Always keep to the instructions contained in this manual. CAUTION Non compliance with the CAUTIONs and/or the instructions may damage the tester and/or its components or injure the operator. Before changing the switch position, take off the clamp jaw from the tested conductor or the electrical circuit in order to avoid any accident When the clamp is connected to the circuits to be tested, never touch unused terminals When testing resistors, do not add voltage.
HT9019 2. GENERAL DESCRIPTION HT9019 meter can perform the herewith measurements: DC and AC TRMS Voltage up to 1000V AC TRMS Current up to 1000A Resistance and continuity test with buzzer AC voltage detection with and without contact with integrated sensor Each parameter can be selected by rotating the 7 positions switch. To abilitate the hold function the HOLD key is available. There are also the following keys: “MODE "MAX/MIN", “REL”, “PEAK” and “ ”. For their use please see § 4.2.
HT9019 3. PREPARATION FOR USE 3.1. INITIAL The tester has been checked from a mechanical and electrical point of view before shipment. Every care has been taken to make sure that the instrument reaches you in perfect conditions. However, it’s advisable to make a rapid check in order to detect any damage which may have occurred in transit. Should this be the case, enter immediately the usual claims with the carrier. Make sure that all the accessories listed in § 6.3 are contained in the package.

HT9019 4.2. FUNCTION KEY DESCRIPTION 4.2.1. H key By pushing “H” key the parameter measured value is frozen on the display and the symbol ”HOLD” appears on it. This mode is disabled by pushing “H” key or moving the rotary switch. key 4.2.2. Keep pressed the “H” key for the backlight activation. This light could help the operator reading the display while he’s measuring in dark sites. For sake of battery saving after 10 seconds the light is automiatically switched off. 4.2.3.
HT9019 4.3. FUNCTIONS OF ROTARY SWITCH DESCRIPTION 4.3.1. AC Voltage measurement CAUTION Maximum input for AC Voltage measurements is 1000Vrms. Do not take any voltage measurement exceeding this limit in order not to risk electrical shock or damaging the tester Fig. 3: Taking AC voltage measurements 1. Rotate the switch on position 2. Insert the red test lead plug into V jack and the black test lead plug into COM jack (Fig. 3) 3.
HT9019 4.3.2. DC Voltage measurement CAUTION Maximum input for DC Voltage measurements is 1000V. Do not take any voltage measurement exceeding this limit in order not to risk electrical shock or damaging the tester. Fig. 4: Taking DC voltage measurements 1. Rotate the switch on position 2. Insert the red test lead plug into V jack and the black test lead plug into COM jack (Fig. 4) 3. Connect the two long ends of test leads to the desired circuit, then reading will be displayed 4. When “O.L.
HT9019 4.3.3. Resistance measurement and Continuity test CAUTION Before taking any in circuit resistance measurement, remove power from the circuit to be tested and discharge all the capacitors. Fig. 5: Taking Resistance measurement and Continuity test 1. Rotate the switch on 2. Insert the red test lead plug into V jack and the black test lead plug into COM jack (Fig. 5) 3. Connect the two long ends of test leads to the desired circuit, then reading will be displayed 4.
HT9019 4.3.4. AC Current measurement CAUTION Make sure that all the test leads are disconnected from the meter terminals for current measurement. Fig. 6: Taking AC current measurements 1. Rotate the switch on 60A, 600A, or 1000A position 2. Put the conductor to be tested inside to the center of clamp jaw to perform accurated measurements. Consider the notches on jaws as reference (see Fig. 2). The reading will be displayed 3. When “O.L.
