5.2.5.5 Suspend Function
The 6240B can select from three output statuses; Standby (output relay OFF), Suspend HiZ (output relay
ON and high resistance), and Suspend LoZ (output relay ON and low resistance).
Using this function can reduce unnecessary relay ON/OFF actions, which reduces deterioration of the
throughput due to relay operation time and improves the life spans of the relays.
Therefore, using the suspend function is recommended whenever turning OFF the output to change the
source conditions.
Figure 5-11 below shows a conceptual diagram of output status.
