Veris Technologies pH Manager - Operating Instructions - Manual (Page 29)

Pub.# OM17-MSP-pH
3-21
This time warning is to let the operator know that a measurement cycle is requiring excessive time.
While an occasional cycle may exhibit this warning. see the troubleshooting section if this occurs
frequently.
The Veris MSP pH Manager uses two electrodes for optimal data quality. If there is a difference of
0.75 or greater between the final electrode readings, the software will beep and the pH readings
will flash, informing the operator of the erroneous reading.
To pause the data collection process at any time (but keep the same file), press Engage button.
Once the sampling process has completed its cycle, it will disengage and the status text message
will indicate disengaged (press Engage to start cycling again). If the system no longer senses a
speed signal from the GPS, it will also disengage. NOTE: do not depend on the GPS speed signal
for disengagement. Before inspecting or working around any component of the system, press the
Engage key and ensure the engage light is red before exiting the vehicle. Sporadic GPS signals
may simulate movement and initiate the cycling process, resulting in possible entanglement and
injury.
If TAP or DI are selected as the wash water type, the water baseline process will be repeated
every 40 cycles following the next engage press. If the pH during the cycling sequence does not
get within 0.5 of the baseline pH, the computer speakers will beep and the pH labels will blink. This
is to allow operator that the electrodes are not cleaning properly.
pH Data Flags
Numbered “flags” can be added to the pH data by pressing the Flag key or F2 while the pH
Manager is CYCLING or RECORDING. If the key is pressed while the pH Manager is in the
RECORDING phase, the flag light will turn bright green:
Figure 23
This means the flag will be recorded with the current data point. If the key is pressed while the pH
Manager is in the CYCLING phase, the next point will be flagged and exclamation point will not
appear until the RECORDING phase is reached. Tip: Use this function to flag any sample where a
problem has occurred, such as a plugged shoe. Open the pH file in a spreadsheet program, locate
the points that have been flagged, and delete rows of problem data.
There are warning signals programmed into the SoilViewer to warn the operator that data are not
being recorded, so that corrective action can be taken. If data aren’t being recorded, a warning
beep will sound from the computer, and the text indicator of the data that is missing information will
blink. For example, if the DGPS isn’t being received (or the NMEA string containing speed) the Fix
indicator text will blink. If EC values are negative, they will also blink.
