Input Coupling
You can change the input coupling setting to match the signal that you are measuring. By changing the setting,
you can choose how the vertical-axis (voltage-axis) control circuit is coupled to the input signal. The following
types of input coupling are available: DC, AC, GND, TC, DC-RMS, AC-RMS, ACCEL, and OFF.
*
Set the
appropriate input coupling for each input module.
* If you do not want to measure the selected sub channels on a 16-CH voltage input module or a 16-CH
temperature/voltage input module, set them to OFF.
Vertical Zoom
You can zoom the waveform vertically. You can zoom the waveform by setting the vertical magnification or by
setting upper and lower display limits.
Linear Scaling
Linear scaling is a function that converts measured values into physical values and reads them directly. There
two types of linear scaling:
AX+B
Using scaling coefficient A and offset B, the DL850E/DL850EV scales values according to the equation below.
Y= AX + B (where X is the measured value and Y is the physical value)
P1-P2
The DL850E/DL850EV determines the scale conversion equation (y = ax + b) using four values that you specify:
two measured values (P1:X, P2:X) and the value that each one should be converted to (P1:Y, P2:Y).
The DL850E/DL850EV scales values using the scale conversion equation that it determines.

Horizontal Axis (Time Axis)
Time Axis Setting
Normally, under the initial settings, the time axis scale is set as a length of time per grid division (1 div). The
selectable range is 100 ns/div to 20 days/div.
*
As you adjust the value, the unit changes between seconds,
minutes, hours, and days automatically. Because the horizontal display range is 10 div, the amount of time on
the waveform that is displayed is equal to the time axis setting × 10.
* When the 720210 (HS100M12) module is installed, the scale range starts at 100 ns/div; when it is not
installed, the scale range starts at 1 μs/div.
Internal and External Clocks (Time base selection)
Under the initial settings, the DL850E/DL850EV samples the measured signal using the internal clock signal
produced by its internal time-base circuit.
You can also use an external clock signal to control sampling. Apply the external clock signal to the external-
clock input terminal. This external clock input is useful for synchronizing to the clock signal of the waveform that
is being measured.
