5.2 Example for CR10X

;Measure the HMP50 temperature.

;

01: Volt (SE) (P1)

1: 1 Reps

2: 5 2500 mV Slow Range ;CR510 (2500 mV); CR23X (1000 mV); 21X,

CR7 (5000 mV)

3: 3 SE Channel ;Black wire (SE 3), Blue wire (G)

4: 1 Loc [ T_C ]

5: .1 Mult ;See Table 3 for alternate multipliers

6: -40 Offset ;See Table 3 for alternate offsets

;Measure the HMP50 relative humidity.

;

02: Volt (SE) (P1)
