  • Page 5: Introduction

    As with its predecessors, this portable unit has built-in memory that stores readings for later retrieval, however the CheckMate™ can store readings for up to 204 individual probes, with 10 readings per probe. Furthermore, the CheckMate™ makes transferring its stored data to a PC a much simpler process than before, using the included Corrdata CSV program.

  • Page 16 CHECKMATE™ Clearing Memory on CheckMate™ Normally it will not be necessary to clear the memory on the CheckMate™ unless extraneous entries have been made, for example, when initially experimenting with the system. Alternatively, if the equipment is to be transferred to a new location, then it is recommended to clear the memory to avoid confusion with any previously collected data.
  • Page 17 READING ER PROBES CHAPTER 5 Reading Electrical Resistance Probes Electrical Resistance probes can be read using three different procedures: Quick, ID and New. The Quick reading allows the user to read a probe and view the result in approximately 30 seconds.

    A series of > symbols will accumulate from left to right across the display to indicate the progression of the measurement function At the conclusion of the measurement function (approximately 30 seconds) the CheckMate™ will display the probe reading and the check reading in divisions. A typical displayed reading is shown below: The Div: reading is the cumulative metal loss (corrosion) of the probe element on a scale of 1,000 divisions.

  • Page 19: Table

    READING ER PROBES The Chk: reading is a measure of probe functionality or integrity. The initial value for ER probes is 800 ±50 divisions. It is recommended that a CHECK reading be taken and recorded immediately after unpacking a probe as it will be the value to which all subsequent CHECK readings will be compared.
