Rev 1 – July 2018 Cath-Tech Hexcorder Pro ManualPage 13 of 38Interruption Cycle & Timing SettingsFigure 13 - Cycle & Timing ScreenCycle TimeSet the cycle time to match the same settings you have applied on your current interrupters.The cycle time must be evenly divisible into 60 seconds. Common cycles are 1s, 2s, 4s, 5s, etc.OFF TimeThe OFF time is set by the user, which should match the off time used by the currentinterrupters. Typically, the OFF time is about ¼ of the total cycle time. The ON time iscalculated from the cycle time minus the OFF time.ON/OFF FirstThe Hexcorder Pro can measure the OFF or the ON measurement first. Most interruptersfunction with the OFF occurring at the start of the cycle. Select the correct setting to matchYOUR interrupters.Delay TimesThere are six delay time options for controlling the exact time that the Hexcorder Pro takes itsmeasurements within a cycle. The delay times are in milliseconds and are timed from the startof their respective portion of the cycle.In GPS synchronized mode, the use of delays can improve survey accuracy. When the cathodicprotection is first turned on or off, there can be an inductance spike in the voltage due to thecapacitance of the coating. A more accurate reading can be obtained by delaying the reading,instead of taking the reading right as the rectifiers turn off. Inductive spikes can be seen on anywaveforms taken, this information can be used to adjust delay settings accordingly.The Hexcorder Pro will notify the user of any errors when the settings are saved. |
