The Extech 412355A has the ability to display different current meter ratings in mA or as a percentage of the 0 to 24mA range, which can be changed in the settings area of the menu, or displayed as mV in the voltage ranges. The calibrator can also provide an adjustable calibration sources from 0 to 10V or 0 to 24mA.

The design of the Extech 412355A is user friendly making you more efficient at your job by being able to control your device with just one hand, leaving the other free to complete any other task. The oyster case has a flip up display that makes this product perfect for holding in one hand or placing on top of a benchtop when you need to note down any of the current meter measurements that have been taken. For added ease of noting them down, the device can also store up to 5 calibration values that can be recalled later.
