16.Code Setting
・ In go sampling (in the Multi-Hold mode), the operation ch is incremented by one when:
・ The operation ch can be updated 8 times at maximum.
・ The operation ch is automatically updated until it is repeated 8 times or the Auto Code
・ The operation ch is not updated after it reaches 31ch.
・ In the Auto Code Up mode, changing the operation ch by external input is ineffective.
・ When the Hysteresis mode is set, it functions only when:
・ After completion of sampling, the operation ch is fixed at the last operation ch. By
・ In the Auto Code Up mode, reset operation of each hold by the T/H signal or H/M
・ The Auto Code Up mode can be cancelled not only by turning on the START signal but

and in return sampling, when:
X-axis value ≦ Code up point.
(X-axis value: Sampling time when the Multi-Hold mode is set, and X-axis measured
value when the Hysteresis mode is set.)
Up corresponding to the changed operation ch is set to "OFF".
X-axis measured value < 10000.
turning on the START signal at the next sampling, the Auto Code Up mode is
canceled, and the mode in which the operation ch is changed by external signals is
brought about. (After sampling starts, check the auto code up setting again.)
signal is ineffective. Therefore, each hold can be executed simply by keeping the T/H
signal or H/M signal ON.
also by turning on the input "Reset Auto Code Up" (See "4-3-2. Input and Output
Signals" P25.) after completion of sampling.
