Helios PD2-6100 Strain Gauge, Load Cell, and mV Meter
Select Menu (SElect)
The Select menu is used to select the input signal
conditioner applied to the input (linear), low-value
cutoff, Auto-zero, and analog output programming.
The multi-point linearization is part of the linear
function selection.
Input Signal Conditioning (Functn)
The Function menu is used to select the input signal
conditioner applied to the input: linear. The multi-point
linearization is part of the linear function selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.
Multi-Point Linearization (Linear)
Meters are set up at the factory for linear function with
2-point linearization. Up to 32 linearization points can
be selected for PV under the linear function. The
multi-point linearization can be used to linearize the
display for non-linear signals.
If the dual-scale Level feature has been selected, the
menus for PV1 & PV2 are enabled. PV2 can be
programmed with up to 8 linearization points.
Auto-Zero (Auto 0)
Auto-zero corrects for drift that can occur over time
that causes the input signal to slowly change. The
meter will continue to read zero despite slow and
small changes to the input signal. The auto-zero value
represents the percent of full scale drift that the meter
will correct.
Under normal circumstances, when the signal
increases quickly, by an amount greater than the
auto-zero percent of full scale, the value will not be
adjusted. Slow signal changes that occur over time at
increments less than the auto-zero value, will not
register on the meter (example: dust on a load cell or
sensor drift over time).
Auto-Zero Example
0.00 – 100.00
Scale
Auto-Zero
0.06
Changes less than 0.06 within 1 second are zeroed
out. If the change is 0.10, then it is registered as a
real signal change and the Auto-Zero function is
bypassed.
Low-Value Cutoff (CutofF)
The low-value cutoff feature allows the meter to be
programmed so that below a certain value, the meter
always displays zero.
The cutoff value may be programmed from 0.1 to
999999. The meter will display zero below the cutoff
value. Programming the cutoff value to zero disables
the cutoff feature. The cutoff can be disabled to
display negative values.
