    keyword=Water Calibration summary

    Figure 1 shows a summary for water calibrations from this weekend. The gain setting on the pre-amp was set at 50, 100, and 200x, with the inverse button on and off. Calibraton # 1 was done in April at a gain of 100x and the inverse off.

    Calib. # 2: C_w = 0.07396 +/- 0.00178 mV/(amg*cm^2*%); gain: 100x, inverse: off
    Calib. # 3: C_w = 0.07310 +/- 0.00189; gain: 100x, inverse: on
    Calib. # 4: C_w = 0.07587 +/- 0.00215; gain: 50x, inverse: off
    Calib. # 5: C_w = 0.07461 +/- 0.00120; gain: 50x, inverse: off, spare pre-amp
    Calib. # 6: C_w = 0.07510 +/- 0.00179; gain: 200x, inverse: off
    Calib. # 7: C_w = 0.07596 +/- 0.00175; gain: 200x, inverse: on
    Calib. # 8: C_w = 0.07549 +/- 0.00187; gain: 200x, inverse: off, spare pre-amp
