Configuring TempTC/32B Thermocouple Channels (TempScan/1100 Only)
If the TempTC/32B scanning card is used, 32 differential thermocouple inputs are provided. In
configuring thermocouple channels, all that is required is to assign each channel to a particular
thermocouple type. Support for Type J, K, T, E, R, S, B and N (14 and 28 gauge) thermocouples are
standard. The 100-mV (with and without range-error detection) types are also supported.
Configuring TempV/32B Volts Channels (TempScan/1100 Only)
If the TempV/32B scanning card is used, 32 differential voltage inputs are provided. In configuring
voltage channels, all that is required is to assign each channel to a particular voltage type. Support for
±
100 mV,
±
1 V,
±
5 V, and
±
10 V ranges in DC are standard.
Configuring TempRTD/16B RTD Channels (TempScan/1100 Only)
If the TempRTD/16B scanning card is used, 16 inputs for 3-wire or 4-wire RTDs are provided. In
configuring RTD channels, all that is required is to assign each channel to a particular RTD type, where
channel numbers 17 through 32 on the scanning card are not used.
Configuring MTC/24 Thermocouple Channels (MultiScan/1200 Only)
If the MTC/24 scanning card is used, 24 differential thermocouple inputs are provided. In configuring
thermocouple channels, all that is required is to assign each channel to a particular thermocouple type.
Support for Type J, K, T, E, R, S, B and N (14 and 28 gauge) thermocouples are standard.
Configuring MTC/24 Volts Channels (MultiScan/1200 Only)
If the MTC/24 scanning card is used, 24 differential voltage inputs are provided. In configuring
voltage channels, all that is required is to assign each channel to a particular voltage type. Support for
± 100 mV, ± 1 V, ± 5 V, and ± 10 V ranges in both DC and AC are standard.
Note: The above AC ranges are maximum peak-to-peak signals for AC volts. Vrms values are
accurate to 70.7% of peak value.
Note: The MultiScan/1200 unit only supports the measurement of AC voltages where the frequency
of the input signal is an integer multiple of the AC line cycle. Consequently, sampling
weights less than 32 can yield incorrect results. In order to compute an accurate Vrms value,
you must program a frequency which will yield a sufficient even integer number of samples
per line cycle.
Configuring MHV/24 High-Voltage Channels (MultiScan/1200 Only)
If the MHV/24 scanning card is used, 4 differential high-voltage inputs are provided. In configuring
high-voltage channels, all that is required is to assign each channel to a particular voltage type.
Support for ±2.5 V, ±25 V, and ±250 V ranges in both DC and AC are standard.
Note:
The above AC ranges are maximum peak-to-peak signals for AC volts. Vrms values are
accurate to 70.7% of peak value.
Note: The MultiScan/1200 unit only supports the measurement of AC voltages where the frequency
of the input signal is an integer multiple of the AC line cycle. Consequently, sampling
weights less than 32 can yield incorrect results. In order to compute an accurate Vrms value,
you must program a frequency which will yield a sufficient even integer number of samples
