Manual revision 016 Section 4: Deploying and Operating FastCAT SBE 49

Polled Sampling Commands

PumpOn Turn pump on. Use this command:

• Before sending TS to obtain pumped

conductivity data, or

• To test pump.

PumpOff Turn pump off.

TS Take 1 sample and transmit data.

Testing Commands

The FastCAT takes and transmits data for 100 samples for each test. Press the

Esc key or Stop on the Toolbar to stop a test.

TT Measure temperature, transmit

converted data.

TC Measure conductivity, transmit

converted data.

TP Measure pressure, transmit converted data.

TTR Measure temperature, transmit raw data.

TCR Measure conductivity, transmit raw data.

TPR Measure pressure, transmit raw data.

Note:

Testing commands do not

automatically turn the pump on. Thus,

they report conductivity from

essentially the same sample of water

for all 100 samples, because the

pump does not run and water does

not freely flow through the conductivity

cell. To get conductivity from fresh

samples, send PumpOn before

sending TC or TCR, and then send

PumpOff

when the test is complete.
