LDARtools phx42 - Weekly Probe Integrity Inspection; Probe Hose Construction

UNCONTROLLED IF PRINTED 26
Creating Daily Calibration Reports
The phx42 does not automatically create daily calibration reports when the device is manually
calibrated. A SpanBox5 with Cal5.0 is required for digital calibration records to be created for
reporting purposes.
For assistance upgrading to a SpanBox5 for the phx42 contact sales@ldartools.com.
Filter Detection
phx42 is designed to inform you if you are attempting to operate without a filter. The phx42 is set to
detect a certain vacuum and will not operate if this specific pressure is not met.
To calibrate your filter detection value
Run a self-check through the phxApp and follow the prompts using a .22-micron filter (LDAR#4236)
When to calibrate your filter detection value
There are three times you should recalibrate your filter detection value:
1. If you see the error: “Feels like you just removed my filter. Please give me a fresh filter so we can get
back to work.”
2. If you notice the pump DOES NOT turn off when replacing the filter throughout the day.
3. At a minimum, once per month if you routinely use Cal5.0 for daily calibrations.
Responding to a failed filter calibration
If you are unable to calibrate your filter, do a probe integrity inspection (see procedure). Report an issue,
including the results of the probe integrity inspection in the comments section.
FAQ
What do I do about slow recovery during Daily Calibration?
If, during the confirmation phase after Daily Calibration, it takes more than 2 minutes to recover
to the 2 PPM level, you can recalibrate to Zero by clicking the Cal Zero button in the phxApp.
I must use On-Demand Regulators, is there anything I can do?
If you must use On-Demands, apply the gas 20 seconds before starting the calibration. Even if
you can calibrate, you will experience drift issues.
Are there any special considerations when calibrating an extension probe?
The standard response time is 1 second per foot. When calibrating an extension probe adjust
the response time according to probe length (max of 20 ft).
