Scan Timing

Scan Timing

The following modules acquire data by using relays to switch and scan input channels:

• U8550 Voltage/Temp Module

• U8551 Universal Module

• U8552 Voltage/Temp Module

• LR8530 Wireless Voltage/Temp Module

• LR8531 Wireless Universal Module

• LR8532 Wireless Voltage/Temp Module

• LR8533 Wireless High Speed Voltage Module

All input channels are scanned within the set data refresh interval.

Scanning starts with CH1 and then proceeds in order through all channels for which measurement

is enabled (CH1 → CH2 → CH 3, etc.). Once the next data refresh interval has elapsed, sampling

starts with CH1 again.

The scan duration per channel varies with the measurement module type, number of channels in

use, data refresh interval, power supply frequency filter, and wire break detection setting.
