Introduction
KAIWEETS HT206B is a digital True-RMS clamp meter with automatic range selection.
The Low Impedance (Low-Z) mode can detect and eliminate ghost or stray voltages.
Safety Information
Warnings: Read First
To avoid possible electric shock or personal injury, please obey the following instructions:
• Use the Meter only as specified in this manual or the protection provided by the Meter might be
impaired.
• Avoid working alone so assistance can be rendered.
• Never measure AC current while the test leads are inserted into the input jacks.
• Do not use the Meter in wet or dirty environments.
• Inspect the test leads before use. Do not use them if insulation is damaged or metal is exposed.
• Check the test leads for continuity. Replace damaged test leads before using.
• Use extreme caution when working around bare conductors or bus bars. Contact with the conductor
could result in electric shock.
• Do not hold the Meter anywhere beyond the tactile barrier.

2
• When measuring current, center the conductor in the clamp.
• Do not apply more than the rated voltage, as marked on the Meter, between the terminals or between any terminal
and earth ground.
• Remove test leads from the Meter before opening the Meter case.
• Never operate the Meter with the back cover removed or the case open.
• Never remove the back cover or open the case of an instrument without first removing the test leads or the jaws
from a live conductor.
• Use caution when working with voltages above 30 V ac RMS, 42 V ac peak, or 60 V dc. These voltages pose
a shock hazard.
• Do not attempt to measure any voltage that might exceed the maximum range of the Meter- 600 V RMS and 1 kHz.
• Do not operate the Meter around explosive gas, vapor, or dust.
• When using probes, keep fingers behind the finger guards.
• When making electrical connections, connect the common test lead before connecting the live test lead; when
disconnecting, disconnect the live test lead before disconnecting the common test lead.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, or diodes.
• Check the operation of the meter at a known source before and after use.

Other Functions
AC voltage measurement with low-pass filter "LPF"
The "LPF” function allows the clamp meter to filter interfering signals of over 60 Hz. These signals
can lead to inaccurate measurements. The meter filters these signals and only measures the voltage signal.
Measurement with LPF:
Set the rotary switch to 600A, 60A or V.
Press the "FUNC." button three times until appears on the display.
Now you can connect test leads and start measurement.
The LPF function is only possible in AC measurement mode.
High-Impedance Voltage Measurement
High Impedance means high electrical Impedance. This is used to denote the input Impedance or output
Impedance of electrical circuits and devices in particular. When measuring in the circuit, this has only
a minor impact on the performance of the circuit, particularly in the case of sensitive electronic
circuits or control circuits.

8
Low impedance voltage measurement (LowZ)
LowZ mode allows you to measure AC voltages with a low impedance (approx. 300 kΩ).
In this mode, the multimeter lowers the internal resistance to prevent ‘phantom’ voltage readings.
As a result, the circuit is more heavily loaded than in the standard measuring mode.
Set the rotary switch to "LowZ" to use the function.
The LowZ voltage measurement must not exceed 600 V.
Due to the reduced impedance, this measurement function is not suitable for continuous
measurement. A max. The measurement duration of 1 minute must be observed.

Operating Instructions
Insert and replace batteries
Replace the batteries immediately when the symbol
appears in the display. Disconnect the meter from the power
source. Remove the test leads from the measuring device,
loosen the screws on the back and remove the lower half of
the housing, replace the old batteries and screw the cover back on.
Turn on/off the meter
The device is switched on when the rotary switch (5) is set to a measuring function. When the
rotary switch is set to OFF, the measuring device is switched off.
Automatic shutdown
No operation in 15 minutes, the clamp meter beeps 3 times. Without further operation, the clamp
meter beeps again and switches off automatically.
Press any key to restore the clamp meter to operating status. The symbol appears on the display.
To deactivate the automatic switch-off, hold down the "FUNC.” key for more than 2

10
seconds and switch on the clamp meter at the same time. The symbol disappears. Restart after
switching off the meter, the automatic switch-off can be restored.
Auto-ranging
The meter automatically selects the measuring range that is best suited for the measurement
performed. The measuring unit and resolution are adjusted at the same time.
AC Zero Input Behavior of True-rms Meters
Unlike averaging meters, which can accurately measure only pure sinewaves, True-rms meters
accurately measure distorted waveforms. Calculating True-rms converters require a certain level
of input voltage to make a measurement. This is why ac voltage and current ranges are specified
from 5 % of range to 100 % of range. Non-zero digits that are displayed on a True-rms meter when
the test leads are open or are shorted are normal. They do not affect the specified ac accuracy
above 5 % of range.
Connecting Test Leads
Do not test if leads are improperly seated. Results could
cause intermittent display readings. To ensure proper
connection, firmly press leads into the input jack completely.

Making Measurements
AC current measurement
The current is measured via the current clamp (2). The sensors in the current clamp detect the
magnetic field created by current-carrying conductors. You can take measurements on insulated
and not insulated conductors.
The test leads should be disconnected from the measuring device when measuring current.
Proceed as follows to measure the current:
1) Turn the knob to and select Proper range(6/60A or 600A).
2) Press the clamp release lever and open the clamp.
3) Grasp the individual current conductor to be measured and close the current clamp again. The
measured conductor must be placed in the center of the clamp, otherwise additional errors will occur.
Attention
► Do not use the current clamp to surround more than one conductor.
►If the supply and return conductors (e.g. L and N) are measured, the currents will cancel each
other out and no measurement will be displayed. The cables of household
appliances usually contain L and N conductors. A cable separator is required to measure

5. During AC current measurement, press "FUNC.” to display the frequency value or the LPF function
measurement.

Voltage Measurement V (DC / AC)
Voltage above 600 V cannot be measured! When measuring high voltage, pay special attention to safety
to avoid electric shock or injury.
1. Set the rotary switch to , Press the "FUNC.” key to change the AC or DC voltage measurement.
2. Plug the black test lead into the COM socket and the red test lead into the INPUT socket.

To avoid damaging the instrument or equipment, do not input a voltage greater than 10V.
Note:
When measuring capacitance greater than 100uF, it will take a long to measure correctly.
