The Comtest RS530 breaks all 25 interface lines and has access sockets on both sides of the switch, making it possible to break and crosshatch all lines by means of the switches and jumper cables. Two dual gender ribbon cables assure 100% connectivity in any type of configuration. All contacts are gold plated to ensure good electrical contact.
The, "in-line", high speed monitors test the signal as set by the standard (200mV). The unassigned monitors allows tests for realistic (0.3/0.6/1/ 2 volt) signal levels. The traps increase the functionality of the unassigned monitors by storing short duration changes.
The Ground Potential Difference test is an important feature needed if different grounds (wall outlets) are used. The “in line” GPD tests for voltages over 2 volts, the V11 monitor/trap allows test of Ground Potential Differences as low as 0.3 volt. The Signal Strength test allows the user to test for signal levels of 0.3, 0.6, 1 and 2 volts of GPD or the balanced interface lines.
It is housed in a ABS plastic case, with the battery compartment on the backside. The logical face plate is easy to read and gives all information needed for testing the interface.
It runs over 20 hours on a single 9 volt battery, or can be powered by an optional 9 volt mains adapter. A small 1.5V, AAA size, battery supplies the current for the DC source.
Size of main unit: 150 x 105 x 20 mm Weight:295 grams.
