Maintenance	Model 6750

5.3.13.1SETTING 100 MV CONTROL VOLTAGE

1.Using a DC voltmeter, connected to measure DC voltage, connect the black lead to the (-) side of capacitor C1. Located near the lower left corner of the circuit board. Connect the (+) lead to the top of resistor R19, located slightly to the left of the center of the circuit board. Note the mV reading (typically no greater than 3 mV).

2.Next, position the Analog A cursor to Max position. Note the mV reading from the top of R19. Use pot R21 located slightly to the right of the center of the circuit board to adjust the mV reading 100 mV higher than minimum reading. Reposition Analog A to Min and re- check Min and Max mV readings.

5.3.13.2SETTING OF 4-20MA OUTPUT

1.Using a digital voltmeter connected to read mA, connect the black lead to #1 4-20mA out (-) and the red lead to #1 4-20 mA out (+).

2.Adjust R41 for 4mA when Analog A is at minimum. Adjust R42 for 20mA when Analog A is at Maximum. Repeat Analog Min/Max until 4-20 mA is achieved.
