Page 8: High Resolution Module
The 4 MHz ceramic crystal oscillator is not present and there is no possibility to connect an external RC oscillator to PSØ9. Thus the PSØ9 can be operated only with the built in RC-oscillator.

Page 9: Connecting The Modules
It is basically connected to the pads A and B (SG_A1 and SG_A2, SG_B1 and SG_B2 are shorted). For the gain and temperature measurement, external resistors Rext1 and Rext2 are connected the pads C and D (also shorted). acam-messelectronic gmbh - Am Hasenbiel 27 - D-76297 Stutensee-Blankenloch - Germany - www.acam.de... -
Page 10: Half Bridge Connection For Solar Applications
So with 1 kOhm strain gauges the load cell shows a total resistance of 2 kOhm. The current into the sensor is reduced by a factor of 2. This option is reasonable in case all the strain gauges are on one side of the load cell. acam-messelectronic gmbh - Am Hasenbiel 27 - D-76297 Stutensee-Blankenloch - Germany - www.acam.de... -
Page 11: Full Bridge
For PICOSTRAIN a full bridge is ideally separated into two half bridges. This wiring can increase the resolution com- pared to Wheatstone bridges by 0.6 bit.

Optionally the LCD driver can be powered by the voltage selected by the on-board jumpers on the motherboard (vol- tage adjustable). The appropriate jumper (J26 (fixed) or J27 (adjustable)) has to be soldered in order to select the source of the LCD’s power supply. acam-messelectronic gmbh - Am Hasenbiel 27 - D-76297 Stutensee-Blankenloch - Germany - www.acam.de... - Page 16 GPIOs 0, 1, 2.
