Recorder Mode
3-5
Available Settings: WR3-FV amp
Off : No signal input is accepted
DC : The FV amp regards 0 V as the threshold value for distinguishing between
High and Low signals.
OC : The FV amp regards 2.5 V as the threshold value for distinguishing
between High and Low signals.
(4) Range ....................... Specifies the range of signal input to be measured. The available settings vary with
the type of amp installed and the INPUT setting. Please refer to Appendix A for the
available ranges for each amp type.
TIP
When the AUTO setting is selected, the measurement range is automatically selected to
suit the signal input. The selected range is determined by the input voltage level at the
time the AUTO setting is selected.
(5) Filter.......................... Selects the filter status.
TIP
• Use the Line filter setting to cut off noise (50/60 Hz) from the power line when such
noise is affecting the signal input.
•
The other filters are low-pass filters. The setting of each lowpass filter is -3dB (typical).
(6) Misc. ......................... Additional settings may be required according to the type of amp installed. Specify
the additional settings as necessary.
WR3-V amp, WR3-M amp, WR3-FV amp
Zero point auto adjustment, zero point adjustment reset, zero point voltage value
WR3-DCB amp
Auto balance, rated output, setting of calibration values
Scaling, Lower - SPAN - Upper, Unit
These items are not available in FFT mode.
(7) Scaling ...................... Displays the setting status of this function in the EU Settings window.
CHECKPOINT
The scaling function cannot be turned on or off using this setting. Scaling on/off functions
and other scaling settings should be set using the EU Settings window.
(8) Lower - SPAN - Upper Unit
............................. Set the span of signals to be measured within the currently selected measurement
range. The table below lists the standard SPAN values that can be specified. When
setting SPAN values, be sure to set the Upper SPAN value so that it is greater than
the Lower SPAN value. When the ENTER key is pressed while this parameter is
selected by the cursor, the following window appears.

Upper: +250.0 [ +250.0 ]
Lower: —250.0 [ —250.0]

(a) Input the Upper-limit SPAN value here. When the Scaling setting is On, this
SPAN setting is also scaled.
(b) Input the Lower-limit SPAN value here. When the Scaling setting is On, this
SPAN setting is also scaled.
