Datasheet Seaward RH9A Series

RH9A Series Key Features 1, 3, 6 & 9 decades available

Range 1 kilo ohm to 1 tera ohm Max Voltage 5kV

Accuracy ± 0.1%

Portable caseHigh resistance, high voltage decaderesistance box with SP1 switchDesigned using the Cropico high quality SP1 switch combined with specially selectedresistors, this range of high ohm resistance decades is ideal for the calibration of insulationtest sets having a voltage rating up to 5kV. Housed in a rugged carrying case and availablein either 3, 6, or 9 decades the RH9A series covers the range 1 kilo ohm to 1 tera ohmand is equally at home in the laboratory workshop or field application. A single decade unitis also available with 10 switched values from 1 kilo ohm to 1 tera ohm.Supplied complete with high voltage test leads 1metrein length and calibration certificate.
