Trend Screen
Displays the waveform of the measured and computed data. The direction of the
waveform display can be set to horizontal or vertical. For details related to the display
method, see section 4.3.

Updating the waveform and updating the numerical display
One division on the RD-MV100 consists of 30 dots on the LCD. The displayed waveform
is updated at an interval corresponding to one dot. This interval is determined by the
time period corresponding to one division (referred to as the display update rate). The
relationship between the display update rate and the speed of movement of waveforms
is as follows:
Display Update 1 min 2 min 5 min 10 min 20 min 30 min 1 h 2 h 4 h
Rate (/div)
Speed of movement 594 297 119 59 30 20 10 5 2.5
(approximate value, mm/h)
Note
The speed of movement of the trend display along the time axis is derived from the following
equation given the dot pitch of the LCD (0.33 mm):
The speed of movement of the trend display along the time axis = 30 (dots)

(min)/display update rate (min)
Measured and computed values are updated every second. However, when the scan
interval on the RD-MV106/RD-MV112 is 2 s, the display update rate is also 2 s.
