Accuracy tables

"Absolute measurement error" service allows you to estimate the measurement accuracy considering uncertainty (error) in the absolute value. It's important if you take measurements at the range edge when the error value contributes to the value displayed on the device screen.

To get the value range it'd be enough to enter the estimate of the value under measurement into Value input field and to see the range of possible values taking all of the standardized errors into consideration.

Note: a point is used as a separator of the integer and fractional part.

AC+DC 1φ2W Power(W) and Power Factor (PF) measurement

Note: Do not clamp on to any conductor when turning on the power of power clamp, because the power clamp is designed to auto zero any residual magnetic field in the jaws at the moment the power clamp is turned on. Clamping around a conductor and powering the instrument up will produce inaccurate readings. ALWAYS power the instrument up prior to clamping around a conductor!

1. Turn the clamp on with the jaws clamped on to no conductor.
2. Set the rotary switch to W
3. If the watt reading is not zero, press the DCA/DCW ZERO button once to zero the watt reading
4. Insert the test leads into the input terminals.
5. Connect the test probe of COM (black) terminal to the neutral line.
6. Connect the test probe of V (red) terminal to the power line.
7. Clamp on to the conductor where V (red) terminal is connected.
8. The power clamp will automatically select the appropriate range.
9. Read the Watt and PF values displayed in the LCD.

AC+DC Voltage Measurement

Note: Maximum input for DC V is 1000, and for AC V is 750. Do not attempt to take any voltage measurement that exceeds these limits. Exceeding these limits could cause electrical shock and damage to the clamp meter.

V + Hz Dual Display

1. Set the rotary switch to V
2. Insert the test leads into the input terminal.
3. Connect the test probes of the test leads in PARALLEL to the circuit to be measured.
4. The clamp will automatically select the appropriate range.
5. Read the voltage and frequency values displayed on the LCD.

AC+DC Current Measurement

Note:

• Do not clamp on to any conductor when turning on the power of power clamp.
• Make sure that all the test leads are disconnected from the power clamp's terminals for current measurement.

The sensitivity for current frequency measurement is 5A, and the frequency range is 10 - 400Hz. If the frequency is < 10 Hz, the LCD will show 0 Hz. If the frequency is > 400 Hz, the LCD will show “OL”.

1. Set the rotary switch at A
2. Push and hold the DCA/DCW ZERO button once to zero the reading.
3. Press the trigger to open the jaw and fully enclose the conductor to be measured. No air gap is allowed between the two jaw halves.
4. The clamp will automatically select the appropriate range.
5. Read the current and frequency values displayed in the LCD.

Phase Angle Measurement

1. Make sure the current reading is zero by setting the rotary switch to A. If the current reading is not zero, press the DCA ZERO button.
2. Set the rotary switch to Phase.
3. Insert the test leads into the input terminals.
4. Connect the test probe of the COM (black) terminal to the reference line.
5. Connect the test probe of the V (red) terminal to the voltage signal to be detected.
6. Clamp on to the conductor where the V (red) terminal probe is connected.
7. If a current signal is detected by the jaws, the phase angle will be displayed in degrees in the LCD together with the frequency of the voltage.
8. If a current signal is not detected by the jaws, only the frequency of the voltage will be displayed while the phase angle is left blank.
