VCT1000 Voltage and Current Tester

Product Information

The Triplett VCT1000 Voltage and Current Tester is a feature-packed device that comes with Phase Rotation Indication and Non-Contact AC Voltage Detection. The product has double insulation or reinforced insulation and is CE compliant. It should not be handled by children as it contains hazardous objects and small parts that can be swallowed. The product comes with an LCD display and LED indicators for voltage display, AC voltage, positive/negative DC voltage, warning voltage, right/left rotation direction, and continuity. It also has a flashlight and hold button, non-contact voltage detector sensor, open jaw clamp, and black/red test lead input.

Product Usage Instructions

Before using the tester, refer to the instructions manual carefully. Ensure that the batteries are not expired or damaged, and if so, replace them. Do not leave batteries and packing material unattended as they can be dangerous for children. Remove the batteries if the device is unused for an extended period of time. Use suitable hand gloves while handling cauterized batteries. Do not throw batteries into the fire.

Use personal protective equipment while working near live electrical circuits. Check the voltage range of the tester before use to ensure it is in working order. Factors such as voltage source, shielded wires, and other elements may affect reliable operation. If there is any uncertainty, use other methods to verify live voltage.

Check if the tester is operating correctly before use. If in doubt, replace the tester. Use approved personal protective equipment when working near live electrical circuits.

The product comes with an LCD display that shows auto power-off (APO) on indicator, auto range mode, alternating current (AC A symbol), negative sign (-), direct current (DC A symbol), measurement display (current, %, and frequency), percent symbol (duty cycle), Hz symbol (frequency), amperes (amps) symbol, continuity symbol, ohms symbol (resistance), voltage symbol (volts), measurement display (volts, continuity, ohms), direct voltage symbol (DC V), negative sign (-), alternating voltage symbol (AC V), right phase indicating symbol (R), live voltage present symbol (30V), left phase indicating symbol (L), low battery indicator, and data hold symbol.

For test preparation, insert the black and red test lead inputs into the device’s appropriate sockets. Use the non-contact voltage detector sensor and open jaw clamp to detect voltage and current respectively. Use the flashlight and hold button for better visibility in low light conditions.

Safety Information

Caution! Refer to the explanation in this Manual
Double Insulation or Reinforced insulation

CE Compliance
This device must not be handled by children. It contains hazardous objects as well as small parts that can be swallowed. Do not leave batteries and packing material unattended; they can be dangerous for children. If unused for an extended period of time, remove the batteries from this device Expired or damaged batteries can cause cauterization on contact with the skin; use suitable hand gloves in such cases. Ensure that the batteries are not short- circuited. Do not throw batteries into the fire.

WARNINGS

Read understand and follow safety rules and operating instructions in the manual before using this tester.
The tester’s safety features may not protect the user if not used in accordance with the manufacturer’s instructions.
Check on a known live source within the rated AC voltage range of the tester before use to ensure it is in working order.
Insulation type and thickness, distance from the voltage source, shielded wires, and other factors may affect reliable operation. Use other methods to verify live voltage, if there is any uncertainty.
Do not use if the tester appears damaged or if it is not operating properly. If in doubt, replace the tester.
Do not use on voltages that are higher than as marked on the tester.
Use caution with voltages above 30 volts AC as a shock hazard may exist.
Comply with all applicable safety codes. Use approved personal protective equipment when working near live electrical circuits

Operation

Test Preparation

NOTE: Prior to every test, please ensure that the instrument is in perfect condition:

For example, keep an eye out for a broken housing or leaking batteries.
Always carry out a function test before using the voltage tester, see below.
Check that the instrument is functioning properly (for example at a known voltage source) before and after every test.
If the safety of the user cannot be guaranteed, switch off the instrument and secure it to prevent unintentional usage.

Power ON/OFF

In the OFF state, press the Power/Mode Button to turn ON
In the Power ON state, press and hold the Power/Mode Button to shut down/power OFF

AC Current Measurements

Put a single conductor/wire in between the opening of the open jaw clamp and the LCD will display the current measurement value.
Place the wire in the correct position of the open jaw current clamp otherwise the measurement will be inaccurate.
The LCD will display the reading.

Voltage Measurements

Connect both test probes with power source.
The voltage is displayed via LEDs below the measured voltage value will light up, the different indicating signals of the voltage detector (including the ELV limit indication) are not to be used for measuring purposes,
the voltage is also shown on the LCD display.

For AC voltage, the “AC” is illuminated; For positive voltage, the “+” is illuminated; For negative voltage, the “-” is illuminated.
In the case of DC voltage, the polarity of the indicated voltage relates to the voltage tester probe tip.
Once the safety extra-low voltage (50VAC/120VDC) is reached or exceeded, the “ ” is illuminated, in the event of no battery power or main circuit failure.
Once voltage is applied to the measuring instrument, press the
HOLD Button, the LCD and LEDs display shows the recorded reading; To delete the recorded value, press the HOLD Button once again.

Phase Sequence, Rotation (Rotary Field) Measurements

NOTE: Effective for voltages greater than 80Vrms.

The voltage testers are equipped with a double-pole rotary field indicator.
The rotary phase indication is always active, the symbols “R” or “L” are always displayed, however the rotary direction can only be determined within a thee-phase system, here the instrument indicates the voltage between two external conductors.
Connect the instrument Red Test Lead (L2+) with the supposed phase L2 and the Black test lead (L1-) with the supposed phase L1, the voltage and the rotary field direction are displayed.
“R”signifies that the supposed phase L1 is the actual phase L1 and the supposed phase L2 is the actual phase L2, “L” signifies that the supposed phase L1 is the actual phase L2 and the supposed phase L2 is the actual phaseL1.
The test result table is as follows:

TRIPLETT-VCT1000-Voltage-and-Current-Tester-fig-6

Resistance Test

The Tester measures low ohm resistances between 1Ω and 1999Ω at a resolution of 1Ω.
Note for Resistance test to make sure the UUT (Unit under test) is not live.

Continuity Test

Note for Continuity test to make sure the UUT (Unit under test) is not live.
The continuity test is only possible when batteries are installed and in good condition, a signal sound is audible for continuity and the LED for continuity LED is illuminated.

NCV Test

NCV cannot measure voltage, it can only sense whether there is voltage.
NCV-induced voltage is not less than 100V., it can only sense AC voltage.

Cleaning

Prior to cleaning, remove the voltage test from all measurement circuits.
If the instruments are dirty after daily usage, it is advisable to clean them by using a damp cloth and a mild household detergent.
Never use acid detergents or dissolvents for cleaning.
After cleaning, do not use the voltage tester for a period of approx.

Battery Replacement

When the battery symbol appears on the screen, replace the battery.
Completely disconnect voltage tester from the measurement circuit.
Remove discharged screw, battery cover and batteries.
Replace by new batteries, two type “AA” by respecting correct polarity.
Close the battery cover and re-screw the screw.
