please note that the channel 1 is relative to the channel 6, channel 2 to channel 7 (or
channel 1 is relative to the channel 11, channel 2 to channel 12) and so on.
※
Note: Setting range of scanner card is only limited on DCV, DCI, ACV, ACI, Frequency, Period,
Resistance ,and RTD functions. OP-41T also supports Thermocouple measurement. As to the
current measurements, users can install current shunts on the circuit board to allow indirect
AC and DC current measurements to be made through current shunts only.
Remark 1: In the default situation, current shunts are not installed in the scanner card.
Remark 2: When the current shunts are installed the channels will be limited to the current
measurement unless users release the shunts.
※
Note: The Information regarding the Limitation of Input Signals in Scanner Card is in the
following statement.
10 Channels: 10 channels of 2-pole relay input. All channels configurable to 4-pole.
CAPABILITIES: Multiplex one of ten 2-pole or one of five 4-pole signals into DMM.
20 Channels: 20 channels of 2-pole relay input. All channels configurable to 4-pole.
CAPABILITIES: Multiplex one of twenty 2-pole or one of ten 4-pole signals into DMM.
