The device is designed to test residual current devices (RCDs) of AC, A types. The RCD type and its rated differential current are set manually in the device. All types of RCDs that do not have an operational amplifier with threshold values can be checked using the device offline, for example, when buying, without connecting voltage to the mains.
The device is powered by five 1.5 V AA batteries.
Operating temperature range from -15 to +55 0C.
Calibration interval 2 years.
The device is designed to test residual current devices (RCDs) of AC, A, B types. The RCD type and its rated differential current are set manually in the device. All types of RCDs that do not have an operational amplifier with threshold values can be checked using the device offline, for example, when buying, without connecting voltage to the mains. There is a function for measuring the resistance of the phase-zero loop from 0.4 to 60 ohms. PZO-510 is equipped with magnetic holders, which allows, if necessary, to quickly mount the device on steel surfaces, including those with paint and varnish coatings.
The instrument is powered by a NI-MH 6 V 2A/H battery or five 1.5 V AA batteries.
Using the IFN-300 device, it is possible to measure the resistance of the "phase-zero", "phase-phase" loop and the transition resistance of contact connections. Using the data obtained, it is possible to identify malfunctions in group lines and carry out a set of measures in a short time to avoid serious accidents and fires.
Measurement of the "phase-zero" loop is carried out during acceptance testing of equipment at the request of controlling organizations or periodically - once every 3 years.When measuring the loop resistance "phase-zero", "phase-phase", the device simultaneously measures the active, reactive and impedance of the loop, and also calculates the predicted short-circuit current without disabling the line protection. This is necessary to check the correctness of the set nominal value of the short-circuit protection element (circuit breaker or fuse) and determine the timely operation of this protection. The body of the device is equipped with magnetic holders, which allows, if necessary, to quickly mount the device on steel surfaces, including those with paint and varnish coatings.
Measurement of the resistance of grounding elements, metal connections, continuity of protective conductors using a two-, three- or four-wire method.
Measurement of soil resistivity.
Measuring the resistance of a single grounding conductor in a multi-element grounding system without disconnecting it using measuring clamps (KTI-20/1 or KTI-20/2).
Measurement of the resistance of grounding elements without the use of auxiliary electrodes (GOST R 50571.16) using two clamps (KP-20/1 and KTI-20/1 or KP-20/1 and KTI-20/2).
AC current measurement without breaking the circuit.
Measurement of AC voltage (noise).
