Page 2: General Description And Specifications
GENERAL DESCRIPTION AND SPECIFICATIONS The Series AP5103 is a single-channel DIN Mount instrument which is easily configured, rugged, analog based signal conditioner made to operate with traditional Wheatstone mv/V stain gage bridge sensors used to measure force, pressure, torque and other DC strain gage related measurements. The Series AP5103 has an extremely wide DC power input range with user selectable gain, zero and anaolg output making it adaptable to any users sensor application that requires stable, repeatable and noise free analog signals for control or data acquisition. - Page 3 AP5103 SPECIFICATIONS Measurement Range: Adjustable 0.5 mV/V to 10.0 mV/V; nominal full-scale Transducer Types: Conventional 4-arm strain gage bridges, 120 to 10 k ohm Excitation: 2.5 or 5.0, selectable - up to 70mA Power Supply : 11 - 28 Vdc regulated; 2 watts max. Analog Ouput : selectable;...

Page 4: Transducer Connections
TRANSDUCER CONNECTIONS The Series AP5103 I/O CONNECTIONS are via non-removable screw terminals which will accept wire sizes from AWG 12 to 26. NOTE: The recommended transducer cabling would be eight wire, individually shielded, twisted pair - wired as indicated (Fig. 1) Sense lines must be connected at the transducer (as recommended) or at the AP5103 screw terminals - as a minimum. - Page 5 CALIBRATION Calibration of the AP5103 is accomplished by the conventional shunt technique, using an internally installed calibration resistor, or via the "dead-weight" method. Calibration Resistor. If a fixed resistor is shunted across one arm of a strain gage bridge, it produces an unbalance equivalent to that of a particular value of mechanical input.
- Page 6 CALIBRATION (cont.) Set the Coarse Zero and Span controls to the marked label position (<, Min>). Position the front panel switches to the desired settings for the application. Refer to Fig. 2 for details. Connect readout device (i.e. voltmeter) to ANO & A Common. With the transducer unloaded, adjust the Coarse Zero and the Fine Zero control until the desired analog output is achieved.
- Page 7 CALIBRATION (cont.) If the transducer calibration is unknown, the following calculation is useful to calculate an Equivalent Input value for the factory installed, 59K Ohm shunt resistor. This will approximate the value assuming that the mv/V sensititivity and bridge resistance of the sensor are known. Remote Calibration Check.

Page 8: Verification Of Normal Operation
VERIFICATION OF NORMAL OPERATION It is the purpose of this section to aid the user in determining, in the event of a malfunction of which the Series AP5103 is suspected of contributing, whether the instrument is functioning normally or whether it is the source of the observed trouble. In the event the unit requires repair, the user may also contact the factory Service Department or the local Daytronic Representative for assistance. - Page 9 Due to the nature of technology, changes are inevitable.
