CSCL SPOILER - CURRENT INTERRUPTER

• AC & DC interrupter circuits are electrically isolated from rectifier power. 

• Housed in a polycarbonate waterproof enclosure for outdoor use.

• Continuous synchronization with GPS. 

• High accuracy internal real-time clock maintains interruption in the event of loss of satellite signal. 

• Multiple fixed program setup ensures foolproof operation and minimal setup time. 

• Interrupt D.C. up to 50 Amps at 100 Volts. 

• Interrupt A.C. up to 15 Amps at 240 Volts.

The “normally-open” switch allows the meter to display voltage readings in normal operation, but reduces meter input impedance by a factor of 10 when the push button is depressed. If there is ±5% (or more) difference in the display reading, then there is a contact resistance error that requires correction.

Using the IRS-1 during potential surveys enhances performance by reducing the number of inaccurate readings. True potential values may be calculated to provide ‘true’ values in areas having a very dry, frozen, or high resistivity soil.
