Page 10: Operating Procedures
Operating Procedures ■ Initial Setup Keys are used to switch between setup menus, and the amount of time that you hold the keys down for determines which setup menu you move to. This section describes two typical examples. Note: In the following sections, “PV” is used to indicate a present value and “SV” to indicate a set value. - Page 11 Set SV Keys to set the SV to 10.0. Press the Key. Reset PV Operate Start operation Confirming Set Values Set values are effective two seconds after key operation is stopped or when the Key is pressed. H8GN C-69 Preset Counter/Timer...
