Read this manual carefully before using the instrument! Please follow the instructions and procedures described in this manual. They are aimed at allowing you to make the best of your signal calibrator and avoid any personal injuries and/or damage to the instrument. /v-0\ The signal calibrator contains Electrical and Electronic circuits and must be properly recycled or disposed of (in accordance with the WEEE Directive 2012/19/EU). The signal calibrator is designed to calibrate and measure low voltage process signals. To ensure the safety of the operator and the instrument, DO NOT connect the...

To avoid possible damage to the signal calibrator or to the equipment under test: • Disconnect the power and discharge all high-voltage capacitors before testing resistance or continuity. • Use the proper jacks, function, and range for your measurement or sourcing application. • If the message changes to "OL" the range limit is exceeded and the pressure source must immediately be removed from the APM to prevent damage to the pressure transducer inside. • To avoid damaging the pressure module from overpressure, never apply pressure above the rated maximum printed on the module. • To avoid damaging...
