Element Channel Range 0 CHO BIP10V 1 CHO BIP5V 2 CH7 BIP10V 3 CH2 BIPIV When a scan begins with the gain queue enabled the miniLAB 1008 reads the first element sets the appropriate channel number and range and then acquires a sample The properties of the next element are then retrieved and another sample is acquired This sequence continues until all elements in the gain queue have been selected When the end of the channel list is detected the sequence returns to the first element in the list This sequence repeats until the specified number of samples is gathered You must carefully match the gain to the expected voltage range on the associated channel otherwise an over range condition can occur Although this condition does not damage the miniLAB 1008 it does produce a useless full scale reading It can also introduce a long recovery time from saturation which can affect the next measurement in the queue 3 12 miniLAB 1008 User s Guide Functional Details Digital connector cabling Table 3 5 lists the digital I O connector applicable cables and accessory equipment The x in the compatible cable name indicates the length in feet of the cable Table 3 5 Digital connector and accessory equipment Connector type 37 pin D type shielded Compatible cables C37FF x Figure 3 13 C37FFS x Figure 3 14 C37FM x Figure 3 15 Compatible accessory products
