RH9A SERIES Designed using the Cropico high quality SP1 switch combined with specially selected resistors, this range of high ohm resistance decades is ideal for the calibration of insulation test sets having a voltage rating up to 5kV. Housed in a rugged carrying case and available in either 3, 6, or 9 decades the RH9A series covers the range 1 kilo ohm to 1 tera ohm and is equally at home in the laboratory workshop or field application. A single decade unit is also available with 10 switched values from 1 kilo ohm to 1 tera ohm. Supplied complete with high voltage test leads 1 metre in length and calibration certificate.
