  • How can I start using the manual mode of measurement range selection when operating Aktakom ATK-2250 clamp meter?
  • How can I activate the relative measurement mode when using Aktakom ATK-2250 clamp meter?
  • How can I hold max./min. values when operating Aktakom ATK-2250 clamp meter?
  • How can I measure AC/DC voltage with Aktakom ATK-2250 clamp meter?
  • How can I measure resistance or make the continuity test with Aktakom ATK-2250 clamp meter?

  • How can I use AKTAKOM ATK-2250 clamp meter together with an oscilloscope or multimeter?

    AKTAKOM ATK-2250 can be used together with an oscilloscope or external multimeter. Therefore follow the below steps:

    1. Set the rotary switch to A or ~A.
    2. Connect the test leads (they are not included into the standard accessories kit) to + and COM respectively.
    3. Connect these sockets with the similar sockets of the multimeter or, using a special cable, with the oscilloscope socket and the display will show the measured value

    How can I start using the manual mode of measurement range selection when operating Aktakom ATK-2250 clamp meter?

    To use the manual mode of measurement range selection in Aktakom ATK-2250 clamp meter press RANGE button. To return to the automatic mode (its active on default when you power on the clamp meter) press and keep RANGE button pressed for at least 2 seconds.
    Up

    How can I activate the relative measurement mode when using Aktakom ATK-2250 clamp meter?

    To activate the relative measurement mode in Aktakom ATK-2250 clamp meter press REL button. The last measured value will be taken as the reference one, the display will show zeros. The results of the subsequent measurements will be displayed as the difference between the current and reference values. To turn off the function press and keep REL button pressed for at least 2 seconds. This function can not work simultaneously with the function of max./min. values hold.
    Up

    How can I hold max./min. values when operating Aktakom ATK-2250 clamp meter?

    To hold max./min. values when operating Aktakom ATK-2250 clamp meter you need to press Max/Min button. The display will show H and MIN symbols. ATK-2250 will start the measurement process fixing the minimum value from the measured values. If the button is pressed again the device will fix the maximum value ("MAX" symbol). If you press the button once again the clamp meter will return to the normal measurement mode. This function can not work simultaneously with the relative measurement function.
    Up

    How can I measure AC/DC voltage with Aktakom ATK-2250 clamp meter?

    To measure AC/DC voltage with with Aktakom ATK-2250 clamp meter take the following steps:

    1. Set the rotary switch to V or ~ V.
    2. Connect the black cable to COM port, the red one to +.
    3. Connect the probes to the circuit under measurement and see the device readings.

    Note: Measurement of voltage over 600 V rms is not allowed.


    Up

    How can I measure resistance or make the continuity test with Aktakom ATK-2250 clamp meter?

    To measure resistance or make the continuity test with Aktakom ATK-2250 clamp meter take the following steps:

    1. Set the rotary switch to Ω or .
    2. Connect the black cable to COM port, the red one to +.
    3. Connect the probes to 2 points of the circuit under test or resistor. See the readings on the display.
    4. If the circuit resistance is less than 40 Ohm in continuity test you will hear a sound signal.
