Campbell Scientific CS512 Oxyguard Type III Dissolved Oxygen Probe

EXAMPLE 8. Sample Program using P86 and P22 Instructions

45: Do (P86)

1: 41 Set Port 1 High

46: Excitation with Delay (P22)

1: 1 Ex Channel

2: 20 Delay W/Ex (units = 0.01 sec)

3: 0 Delay After Ex (units = 0.01 sec)

4: 0 mV Excitation

47: Do (P86)

1: 51 Set Port 1 Low

48: End (P95)

In the CR200 series dataloggers, use the Portset instruction.

EXAMPLE 9. Sample Program using Portset

Portset (1,1)

Delay(500,msec)

Portset(1,0)

In the CR1000, CR800, CR850, and CR3000 dataloggers, use the Portset

instruction.

EXAMPLE 10. Sample Program using Portset

Portset (1,1)

Delay (1,500,msec)

Portset (1,0)

The above example is not as power efficient as possible and would require AC

power to maintain a sufficient battery charge. If it is necessary to operate an

agitator without AC power available, write the program so that the agitator is

only operated for a short period of time just before the measurement is to be

taken.
