Probe Zero - Extech Instruments TKG100 User Manual

Extech Instruments
The TKG100 is a base gauge offering a simple user
interface packaged in the same custom molded high-
density plastic case with rubber keypad as the other more
sophisticated models. This gauge offers reliable, accurate
thickness readings on mostly steel structures with access
to only one side.
The TKG150 contains all the same features of the
TKG100 plus:
 50,000 (expandable to 100,000) reading
datalogger capacity with complete setup
tracking
 Three pre-set files for linear, grid (row advance)
and grid (column advance)
 Echo-to-Echo
 B-scan

transducer (after the user selects the transducer from the
list) thus eliminating the need for an on-block zero. The
TKG100 and TKG150 will electronically zero the
transducer upon power up and at a particular time during
normal operation. This feature ensures the transducer is
