3.2 Basic Measurement
Select a Measurement Range (RANGE)
1
Select the units with the mV/V switch.
2
Rotate the RANGE knob to select the desired range.
You can select the best range for the voltage you intend to mea-
sure. The range can be set from ±1 mV to ±250 V. The 500 set-
ting is used exclusively for mV ranges.
Do not set the RANGE knob to 500 while the mV/V
switch is set to V.
Move the Pen Position (POSITION)
1
Move the ZERO/MEAS switch to the ZERO position.
2
Rotate the POSITION knob to set the pens’ zero points.
You can adjust the pen zero point and move the pen position.
You can set the zero point (0 V position) by moving the
ZERO/
MEAS switch in the ZERO position.
Example: When using the ±1 mV range, centering the zero point
allows you to measure from -1 mV to +1 mV, while placing it at
the leftmost edge allows you to measure from 0 V to +2 mV.
Set the Paper Feed Speed (CHART SPEED)
You can set the paper feed speed according to the desired recording
time. This setting can be changed while recording is in progress.
1
Select the speed unit with the h/min switch.
• mm/h : Amount of paper feed per hour [mm]
• mm/min : Amount of paper feed per minute [mm]
2
Rotate the CHART SPEED knob to select the desired
speed.
(Example: 300 mm/h)
Lower the Pens (pen lever)
Place the pen lever in the DOWN (bottom) position
to lower the pens.
