Descripción
AKTAKOM ATK-2250 is a reliable, powerful clamp meter with an extended current range (up to 2.5 kA) for the operation in electricity generating units. Max. grip size for a wire: 2.6 x 0.9 in / 65 x 24 mm, grip diameter: 2.2 on / 55 mm. This clamp meter model has an analog output and can be used both as a separate device and within some measurement complex. Frequency range of current and voltage under measurement is extended up to 1 kHz.
"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.

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:
Set the rotary switch to «A» or «~A».
Connect the test leads (they are not included into the standard accessories kit) to «+» and «COM» respectively.
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 (it’s 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 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:
Set the rotary switch to « V» or «~ V».
Connect the black cable to COM port, the red one – to “+”.
Connect the probes to the circuit under measurement and see the device readings.
Note: Measurement of voltage over 600 V rms is not allowed.
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
