Testing Commands
The 19plus V2 takes and outputs 100 samples for each test (except as noted);
data is not stored in FLASH memory. Press the Esc key (or send a break
character) to stop a test.
TC Measure conductivity, output converted data.
TCR Measure conductivity, output raw data.
TT Measure temperature, output converted data.
TTR Measure temperature, output raw data.
TP Measure pressure (strain-gauge or optional
Quartz), output converted data.
TPR Measure pressure (strain-gauge or optional
Quartz), output raw data.
TV Measure 6 external voltage channels,
output converted data.
TVR Measure voltages read by A/D converter,
output raw data.
Column Output
1 – 6 External voltages
7 Main battery voltage / 11
8
Back-up lithium battery voltage /
3.741
9 External current / 333.33
10 Pressure temperature voltage
TF Measure frequency (optional Quartz
pressure sensor), output converted
pressure data.
TFR Measure frequency (optional Quartz
pressure sensor), output raw data.
T38 Measure SBE 38 (secondary temperature),
output converted data.
PumpOn Turn pump on for testing purposes. Use
this command:
• Before sending testing command to
obtain pumped data from sensors
plumbed with the pump, or
• To test pump.
PumpOff Turn pump off for testing purposes.
Note:
Testing commands do not
automatically turn the pump on.
Thus, for instruments plumbed with
the pump, they report data from
essentially the same sample of
water for all 100 measurements,
because the pump does not run but
the pump and associated plumbing
prevent water from freely flowing
through the conductivity cell and
other plumbed sensors (for
example, dissolved oxygen sensor).
To get data from fresh samples,
send PumpOn before sending
a testing command, and then
send PumpOff when the test
is complete.
