The registrars of stress XL423, XL424, record the values of voltage signal in the necessary period.

These instruments are intended for the measurement and the writing into the memory of the values of the signals of alternating voltage to 600 [V]. [Pribory]s they record the values of signal they preserve them before the internal storage of registrar for the subsequent transmission of data on PK. Registrars have the built-in verifying wires with the clamps.
Model XL423 is intended for the single-phase networks
Model XL424 is intended for the three-phase networks

• Obtaining the accurate results of measurements because of the function Of trueRMS.
• Possibility of the record of the values of signal during the long time to 6 months.
• Connection for the sake of PK (RS-232).
• Storage of given before the memory even in the absence batteries.
• Indication of the discharge of batteries, the fitness for work of instrument due to the conditions of high humidity and low temperatures.
