Helios PD2-6100 Strain Gauge, Load Cell, and mV Meter
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
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.

Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from
factory defaults and use the manual as a step by step programming guide, rather than a random approach to
programming. To reset the meter to factory defaults, see Reset Meter to Factory Defaults on page 50. In addition, for
best results, we recommend using the free MeterView Pro software for all programming needs.

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.
