1harmonicOverview of HWT-1000 Tester

The HWT-1000 device can be used to test harmonic current, voltage, analyze various harmonic components, display, record, and print its test and analysis results.

The testing project is

1. The test circuit can be single-phase, single-phase 3-wire, three-phase 3-wire, or three-phase four wire

2. Digital display of voltage/current, effective/ineffective power, phase/force rate

3. Waveform display of voltage/current

4. High harmonic analysis of voltage/current shows

a) Spectral display of high-order harmonic power of voltage/current

Power spectrum display of high-order harmonic power/direction

c) List of harmonic content/phase for each order

d) List of effective values/phases of each harmonic

The test results can be stored in the body or printed using a printer.

2、 Instrument composition structure

1) HWT-1000 main body

Power button: When the F3 button is in the P-OF state, the power automatic shutdown function takes effect, and the power automatically shuts off about 15 minutes after the last button operation is completed.

Power Charge Power/Charging Light

Contrast Adjustment Button: Adjust the contrast of the monitor. Rotate to the right to make it thicker.

°~Vin voltage input interface:

± CT current input interface: This interface is also used for high-voltage current detection in CT.

PRINTER printer interface: used to connect to dedicated printers.

F1~F5 (function keys): Used to implement the functions indicated below the display.

Modal keys:

B-LIGHT backlight switch: used to turn on and off the backlight of the monitor. According to time

The clock will automatically turn off in about 10 minutes.

11DC ADP charger interface: used for connecting dedicated charger HWTA-10. Charging takes about 8 hours.

2) CT Department

Clamp CT

Open handle

Connecting plug (for connecting with the main body)

3、 Precautions for use

1) Need to prevent electric shock

This device is a low-voltage device and cannot be used for testing AC lines above 600V.

Before use, make sure to confirm that the tested circuit is a low-voltage circuit.

2) Need to prevent electric shock

The equipment cannot be used when it is wet with water, and do not operate the instrument with wet hands.

When there is damage to the body and the clamp shaped CT section, please avoid using the instrument.

3) Prevent electric shock and fire hazards

When the current is too high, the CT part is prone to heating up.

Do not use for testing currents exceeding 300A.

4) There is a risk of electric shock

The testing wires are consumables. Before use, check for any errors or damages. When there is an abnormality, it should be stopped from use, repaired or replaced.

5) Risk of burns

1. The wires should be carefully connected to avoid accidents such as sparks.

The input power supply of the dedicated charger (HWTA-10C) is 100V power supply. Misuse of a 200V power supply may cause damage to the charger and body.

3. Charging for too long will shorten the battery life.

4. Do not use other chargers.
