Setting the Input Signal (
Input
)
Enter the
Input
menu to set up the input polarity, range, ratiometric operation, and dual-scale feature.
The meter is capable of accepting any signal from -250 to 250 mV in bipolar mode or up to 300 mV in
unipolar mode.
After selecting “
Yes
” or “
No
” for
ratio
,
d-SCAL
is displayed. Selecting “
Yes
” enables the dual-scale
feature, allowing scaling of the same input in two different scales (for PV1 & PV2) or displaying the
percentage of PV1.
Input Polarity Selection (
PoLAR
)
Select unipolar operation for inputs in ranges from 0 to 300 mV and select bipolar operation for inputs in
ranges from -250 mV to +250 mV. This setting determines the selectable ranges for the millivolt input.
NOTE:
Refer to Switch Configuration starting on page 13 for proper switch positioning.
Range Selection (
RANGE
)
This menu is used to select the input range. The selections listed are determined by the
Polarity
setting.
Unipolar mode:
0-15, 0-30, 0-150, 0-300 mV
Bipolar mode:
±15, ±25, ±150, ±250 mV
NOTE:
Refer to Switch Configuration starting on page 13 for proper switch positioning.
Ratiometric Operation (
ratio
)
Ratiometric operation corrects the measured strain gauge signal for up to
±
5% variation of either the
internal or external excitation power supply. In order to use the ratiometric operation, the ratiometric
operation menu must be set to yes (
YES
).
Dual-Scale (
d-sCal
)
The analog input can be displayed in two different scales, by enabling the dual-scale feature in the
Setup-
Input
menu, see page 25.
To enable the dual-scale feature you must select d-SCAL in the Input selection menu.
If Polarity (

)
Set to Bi (
