Device features • Dimensions: 72 x 72 mm (7204) or 96 x 96 mm (9604/9620)
• Version S for increased shock and vibration resistance• Scale background: white, imprint: black Product description The analogue measuring instruments of the 9604/7204 series are designed for indication of measured values from BENDER devices equipped with the appropriate current output. Measuring instruments for A-ISOMETER® The respective internal resistance of the insulation monitoring device has to be consi-dered. The internal resistance must be equal to the scale centre point (e.g. 120 kΩ). The instruments utilize either a division scale or a scale with a segment display." Standard“ version The enclosures are made of polycarbonate, which is self-extinguishing and of non-mel-ting material (according to UL94V0). For space-saving arrangement, several instruments can be installed close together without spacers. Connection is made via hexagon head
manufacturers of bolts with spring-loaded terminal bolts. The terminals of the
professional enclosure are protected against accidental contact."
Measuring instruments 9604/7204/9620 S“ version The measuring instruments of the "S" series are designed to meet the requirements of harsh environmental conditions, e.g. for use on ships.
