The APT4000 conductivity analyzer series continuously monitors sensor and analyzer-electronics and immediately displays diagnostics when a problem occurs. It indicates the appropriate error code or pictograph, blinks a red LED and adjusts the error current to 22 mA if desired. A manual loop-back check is available to test the integrity of the 4-20 mA output.
The device’s large front display aids quick recognition of process parameters and diagnostics even at a distance. The contacting conductivity analyzer employs visual feedback (pictograph-type characters) that are easily recognized, that alert the operator during process changes and when problems occur. This reduces set up and maintenance times, minimizes calibration errors and makes troubleshooting easy.
