OPERATING INSTRUCTIONS

MODEL 141 ACCELEROMETER

GENERAL INFORMATION

Your Setra accelerometer has been carefully calibrated before shipment to you, and it should be

handled with the same care given any precision instrument. Setra accelerometers are rugged devices,

built to take considerable overrange of “G” loads.

Please refer to the Model 141 calibration data before proceeding further.

CAUTION: BE ABSOULUTELY SURE OF EXCITATION POWER POLARITY BEFORE

APPLYING POWER, REVERSED EXCITATION WILL BURN OUT THE CIRCUIT

INSTANTLY.

MODEL 141A MUST NOT BE OPERATED WITH EXCITATION EXCEEDING 15 VDC.

Model 141A accelerometer excitation voltage 5 VDC to 15 VDC. Keep excitation power between 5 VDC

min. and 15 VDC maximum. High voltage may burn out the circuit. Installation of a protective Zener

diode such as a IN4746A across the excitation power input leads is a good practice, taking care to
