7. Component and Function 7-1. How to Use Hold mode Hold mode is mainly classified into Peak Hold and Sample Hold and according to the intended use (High Speed, Low Speed), Analog, Digital, or Display Hold can be selected. Hold mode can be used by using the Hold key at the front panel or by the external input. For operation method, see the following figure. - Page 13 How to Use Comparison Output Function 7-2. In comparison output function, there are 3 different modes such as Decision, High limit, and Low limit. It displays each setup value (comparison output) at the Relay of the rear panel. In High limit and Low limit modes, Hysteresis can be used. To set the upper limit (High) and lower limit (Low), please use the key on the front panel.
