● Setting example (for the elapsed time display of oven)
Set each setting item for mode and parameter according to the following procedures.
(For the setting method of functions, refer to pages 16 and 17.)
As in the gure on the left, bread passes through the oven in a bread fac-
tory. The rotary encoder is attached to the motor of the conveyor belt. To
display the time at which the bread passes through the oven in DT-501, do
so under the following conditions:
[Conditions]
● Revolution speed of the rotary encoder
●
1200rpm(
rotary encoder
60p/r●
● Speed of the conveyor belt
● 2.8m/min
● Length of the oven
● 5m
● Passing time through the oven
●
5m÷2.8m/min ● 1.786 minutes ●Approx. 1 minute 47 seconds
• Set the mode 2 (elapsed timecounter mode).
• Parameter setting items in mode 2 (elapsed timecounter mode) and numerical values to be set according to the above example.
• Setting method
(1) Mode
(2) Parameter
Press and hold the SHIFT + MODE keys
for 5 seconds or more.
The main display shows the current set
mode No. after blinking.
* When you are setting for the rst time after the
purchase of this unit, mode 1(digital tachometer
mode) in the factory default setting is displayed.
Press the SET key.
The display goes to mode 2 (elapsed timecounter
