Frequently Asked Questions - 10A69-4 Daytronic
How do I connect a strain gage to the 10A69-4?
Use a 4-wire quarter-bridge connection. Connect the excitation lines to the +EXC and -EXC terminals, and signal lines to +SIG and -SIG. Refer to the manual for wiring diagrams.
What is the maximum input voltage?
The maximum differential input voltage is ±10 V. Exceeding this can damage the input stage.
How do I perform a shunt calibration?
Press the CAL button on the front panel. This connects a precision resistor across the bridge to simulate a known strain value. Adjust the gain accordingly.
Can I use the 10A69-4 with a 4-20 mA output?
Yes, an optional 4-20 mA output module can be installed. Contact Daytronic for ordering information.
What power cord does the 10A69-4 require?
It uses a standard IEC C14 power inlet. Supplied with a cord for the region of purchase.
How often should the device be calibrated?
Annual calibration is recommended. Use the built-in shunt calibration for quick checks between full calibrations.
The OVERLOAD LED is lit. What should I do?
This indicates the input signal exceeds the selected gain range. Reduce the input signal or increase the GAIN setting. If persistent, check the sensor or wiring.
Can I daisy-chain multiple 10A69-4 units?
Yes, they can be synchronized using the SYNC connector on the rear panel. Consult the manual for proper cabling.
What is the frequency response of the filter?
The built-in low-pass filter has a cutoff frequency adjustable from 10 Hz to 10 kHz via the front panel potentiometer.
How do I clean the 10A69-4?
Disconnect power. Use a dry, lint-free cloth. Do not use solvents or water. For stubborn dirt, slightly dampen cloth with isopropyl alcohol.
