Isolation Analyser METRISO C
(On batteries operating isolation analyser metriso c with test voltages (up to 1000 V) and a measuring range up to 99.9 GOhm for isolation checking especially on floors and walls)

The isolation analyser metriso c is customized for measurement of electrical equipment, but especially to check the isolation of floorings and walls. The measurement value is directly shown at the isolation analyzer metriso c. The LCD-Display consists of a dot matrix with background lights, which displays the menu, the adjustment facilities, measuring data as well as a help text. The operation language is eligible. The isolation analyser metriso c is easily to handle. A multifunctional key allows a one-hand operation for menu selection and triggering of measurement. The basic- and sub-functions are eligible due to four soft keys. Five different batteries of the isolation analyser metriso c symbols from empty to fully charged clarify he current battery status in the main menu. The analyzer automatically shuts down in case of dead battery. A Charge controlling switch is integrated to monitor the charge of NiMH or NiCd batteries. In case of self-check, test- images can be selected consecutively. Display-LEDs and relays can be tested. The coating with soft plastic protects the isolation analyzer from damage in case of impact or drop. Here you can see all isolation analysers.

Information about Initial and Repeat Test in Power Plants

- Isolation measuring in dead-voltage mode

- Isolation measuring performed only in ranges, which apply to measuring voltage, which means to switch on everything and to measure before and behind switches or bridge every opened contact before measurement and then measure at the feeding

- In case the measuring circuit contains capacitive consumers, discharge after measuring.

- You decide on site, which measuring method should be selected. Short-circuit L + N is often more extensive than single measuring. Those allow conclusions regarding the isolation of the different conductors and by that allow comparisons! Above all a separate measurement of the strands against PE or within is an effective method of precautious fire prevention. RCDs cannot recognize isolation errors between active conductors

- In case of repeat tests always measure L+N against PE (protection of electronic operation devices). Unipolar switched operation devices will be also tested in TN-S/TT/IT systems, without starting them

- During measuring in TN-systems open N-PE bridge, in TT-system disconnect neutral conductor

- During measurement in constructions with voltage arrestors (varistor basis requirement class B or C) those are to be isolated earth-facing. For device protection, e.g. sockets (requirement class D) this procedure is not required. 

- Measuring voltage of 250 V is permitted

- Common values - at initial tests without connected devices > 100 MΩ (see therefor DIN VDE                               0100 part 610)
                           - At repeating test with connected devices ~ 300 kΩ

Knowledge on Resistance of Isolating Floorings and Walls

Knowledge on resistance of isolating floorings and walls
If the compliance with standards according to DIN VDE 0100, part 410/1.97 and in non-conductive rooms is required, at least 3 measurements per location have to be performed. In case of tangible conductive parts in the room, at least one measurement has to be performed in a distance of 1 m from these parts. Measuring methods please review DIN VDE 0100, part 610, attachment A.

Limiting Values

In attachments up to 500 V ≥ 50 kΩ, over 500 V ≥100 kΩ

Important Notice

- In all cases a measuring sensor is necessary (as equipment additional available).

- Please consider DIN EN 1081 - elastic flooring, determination of electric resistance, edition 4/1998 - explosion risk, medically used rooms or the like
