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.
