Recorder Operating Modes
•
“Sleeping”
– Gauge is in a low power mode and is NOT recording data. The
sensors are OFF. Any data in memory is maintained as long as
there is power connected to the gauge.
– Draws 10 – 15 mA when connected to the computer.
– Draws ~0.6 mA when NOT connected to the computer.

Recorder Operating Modes
• “Standby”
– Gauge and sensors are fully powered up, but the gauge is NOT
recording data.
– Draws 40 – 100 mA, depending on the number of channels and
sensors connected to the gauge.
– The mode is typically used to test the battery and sensors for
proper voltages.

Recorder Operating Modes
• “Recording Data”
– Gauge and sensors are fully powered up, and the gauge is
recording data in the “SLOW SPEED” sampling mode.
– Draws 35 – 100 mA, depending on the number of channels and
sensors connected to the gauge.
– When the gauge is disconnected from the computer, it will
continue recording data.
NOTE: The gauge cannot be triggered into “FAST Speed” while it is
connected to the computer.

Recorder Sampling Speeds
Recorder Sampling Speeds
• Multi-Speed Data Recording Modes.
– Fast Speed
• 115,000 data points/second
– Intermediate Speed
• 115 data points/second to 14,700 data points/second
– Slow Speed
• One data point every 10 seconds to 14 data points/second
Multiple recording modes
can be selected
“Recorder Settings”
Menu
Recorder Sampling Speeds
• “SLOW Sampling Speed”
– When the Recorder starts recording data, it begins storing data
at the “Slow Speed” sampling rate.
– The ONLY time the Recorder does NOT start in the “Slow Speed”
is if the “Fast Speed on Startup” has been enabled.
• “FAST Sampling Speed”
– When an “Internal Auto Trigger” occurs (i.e. the pressure exceeds
the programmed threshold), the Recorder begins storing data at
the “FAST Speed” sampling rate (115,000 data points per
second).
Recorder Sampling Speeds
• “INTERMEDIATE Sampling Speed”
– After the “FAST Speed” sampling window has completed, the
Recorder will begin storing data at the “INTERMEDIATE Speed”
sampling rate (if this mode is enabled).
– After the “INTERMEDIATE Speed” sampling window has
completed, the Recorder go back to storing data at the “SLOW
Speed” sampling rate.
– NOTE: The Recorder might go back into the “FAST Speed” mode
before it return to the “SLOW Speed” mode if another “Auto
Trigger” occurs while in the “INTERMEDIATE Speed” mode.
Auto “LOW BATTERY” Shutdown
Auto “LOW BATTERY” Shutdown
• When the Recorder is “Recording Data” and the battery
voltage goes below a safe operating voltage (typ. 4.5 volts),
the gauge will automatically stop recording data and go to
SLEEP (0.5 milliamps).
• This feature ensures that data is not lost if the Recorder cannot
be recovered in a timely manner. In the SLEEP mode, the data
can be maintained in memory for up to 30 days (or longer
depending on the batteries).
NOTE: ALWAYS use an External 9 volt battery for backup power
when you connect the computer to the recorder.

“Power Up” Start will not be activated.
“Start” Options
• “Delay” Start
– Gauge is enabled to “Start Recording Data” after the programmed
delay reaches zero. This count down only occurs while the gauge
is NOT connected to the computer.
NOTE: If the “Kill Switch” is installed, the delay start count down
does not begin until the “Kill Switch” is removed.
– Gauge will NOT start recording data until the count reaches zero
– Draws 8 – 10 mA when the gauge is not connected to the
computer, and while it is counting down.
“Start” Options

“Start” Options
• “Auto” Start
– The Recorder is enabled to “Start Recording Data” after the actual
sensor value (i.e.500 psi) exceeds the programmed threshold.
This only can occur if the Recorder is NOT connected to the
computer.
– In the “Low Power Mode”, the Recorder will “wake up” for one
second, once every 5 minutes, to check the sensor (i.e. pressure)
to see if it has exceed the programmed threshold. If not, the
gauge goes back to sleep for another 5 minutes. If the sensor
value IS above the threshold, and remains above it for 5 – 10
minutes longer, the gauge will start recording data .
– Draws ~0.7 mA when the gauge is not connected to the computer,
and it is checking the sensor.
“Start” Options
• “Auto” Start
– In the “Constant Monitor Mode”, the Recorder continuously monitors the
sensor (i.e. pressure) to see if it has exceed the programmed threshold. If
the sensor value IS above the threshold, and remains above it for the
programmed Threshold Time, the gauge will start recording data .
– Draws 40 - 100 mA when the gauge is not connected to the computer, and
it is checking the sensor.

Downloading the Data
Downloading the Data
•
Always be sure an external 9 volt battery is connected to the interface
box before you connect the computer to the Recorder. This is to
ensure you do not loose data if the internal Recorder battery is LOW.
Downloading the Data
•
If the Recorder is still “Recording Data”, you must first “STOP” the
Recorder, before you can download the data.
Downloading the Data
•
After the Recorder is in the “SLEEP” mode, you can download the data.
Downloading the Data
• Download ALL Data
– Downloads all the data in memory.
• Quick Download
– Downloads only the “Valid Memory” data.
When collecting data, sometimes not all the memory is used to store the
data, so the Recorder keeps track of how much data has actually been
stored in memory. The Recorder will indicate how much data was stored
into memory, and this download option downloads ONLY that data.
NOTE: If in doubt, use the “Download ALL Data” option.
Downloading the Data
• If a “Parity Error” occurs while downloading the data, just try
downloading the data again.
• The data can be downloaded as many times as you want to.
The data remains in memory until EITHER you remove battery
power OR you “START” the Recorder again.
