14 CHECKMATE™
Press Quick (F2) to go to the Select Probe Type display:
Select and press A (F1) for Wire Loop type probes or press B/C (F2) for Tube Loop/
Strip Loop type probes or D (F3) for Cylindrical type probes or G (F4) for Model 610
Atmospheric Probes only. If you are unsure of the element type, this information can be
found on the probe packaging, etched on the probe body adjacent to the connector or in
Table 5.1 Probe Type Identification.
Immediately after pressing the key for the probe type selection the instrument will
automatically go to the “ Measure ” mode and display:
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. In the example above 214.7/1000 (two-hundred fourteen point seven
one-thousandths of the element has been consumed by corrosion. In engineering units
this metal loss would be expressed as 214.7/1000 or 0.2147 times the probe span.
