Troubleshooting Tips
This meter is a highly sophisticated instrument with an extensive list of features and capabilities. If the programming
buttons are used to program the meter, it may be a difficult task to keep everything straight. That is why we strongly
recommend the use of the free
software for all programming activities. A USB cable is provided with
the meter for programming with MeterView Pro software.
If you have programmed the meter with the programming buttons and it is not working as intended, try re-programming
the meter using MeterView Pro software.
Symptom
Check/Action
No display at all
Check power at power connector
Not able to change setup or programming,
Locd
is displayed
Meter is password-protected, enter correct six-digit password to unlock or
Master Password of 508655
Meter does not respond to input change
If a
Low-Value Cutoff
has been programmed, the meter will display zero
below that point, regardless of the input
– which can appear like the meter is
not responding to an input change. Check to make sure the problem is not
being caused by an undesired low-value cutoff setting.
To prevent the display from showing a negative value, set the low-flow cutoff
to a value greater than zero.
Meter displays error message during
calibration (

Check:
1.
Input signal stability and value
2.
Display scaling vs. input signal
3.
Filter and bypass values (increase)
4.
Increase Rounding value

Check filter and bypass values
Display reading is not accurate
Check:
1.
Scaling or calibration
2.
Change Line 2 to mV and check to make sure you are receiving the
correct mV value from sensor
Display value is drifting over time with no
load
Try increasing Auto-Zero value. See
on page
Display does not respond to input changes,
reading a fixed number
Check display assignment, it might be displaying max, min, or set point
Display alternates between

2.
Wiring of relay contacts
Relay and status LED do not
respond to signal
Check:
1.
Relay action in
