1: Do (P86)

1: 48 Set Port 8 High

2: Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (0.01 sec units)

3: 300 Delay After Ex (0.01 sec units)

4: 0 mV Excitation

3: Beginning of Loop (P87)

1: 0 Delay

2: 10 Loop Count

4: Volt (SE) (P1)

1: 1 Reps

2: 25 2500 mV 60 Hz Rejection Range

3: 1 SE Channel

4: 3 -- Loc [ NTU_V_1 ]

5: 0.001 Mult

6: 0.0 Offset

5: End (P95)

6: Spatial Average (P51)

1: 10 Swath

2: 3 First Loc [ NTU_V_1 ]

3: 2 Avg Loc [ NTU_Volts ]

NTU = -0.29928 + (105.69 * NTU_Volts) - (0.24763 * NTU_Volts^2)

; evaluate to see if value >250, where High range measurement should be taken via Sub1
