BFM 0 input mode specification (READ/WRITE)
BFM 0 specifies the input mode of CH1 to CH4. The BFM consists of a 4-digit hexadecimal
code, where one digit is assigned to each input channel. The range for each digit is a Hex
value between 0 to F.
The highest digit corresponds to input ch4, whereas the lowest digit corresponds to input ch1.
code, where one digit is assigned to each input channel. The range for each digit is a Hex
value between 0 to F.
The highest digit corresponds to input ch4, whereas the lowest digit corresponds to input ch1.
The meaning of the digits is as follows:
0: Voltage input mode (-10 to +10 V) (Display range -32000 to +32000)
1: Current input mode (4 to 20 mA) (Display range 0 to +32000) if current is less than 2mA, a
0: Voltage input mode (-10 to +10 V) (Display range -32000 to +32000)
1: Current input mode (4 to 20 mA) (Display range 0 to +32000) if current is less than 2mA, a
range error alarm will be set in BFM 28
2: Current input mode (-20 to +20 mA) (Display range -32000 to +32000)
3: Voltage input mode (-100 to +100 mV) (Display range -32000 to +32000)
4: Voltage input mode (-100 to +100 mV) (Display range -2000 to +2000)
5: Voltmetor display mode (-10V to + 10V) (Display range -10000 to +10000)
6: Amperemeter display mode (4mA to +20mA) (Display range 2000 to +20000 = 2mA to
3: Voltage input mode (-100 to +100 mV) (Display range -32000 to +32000)
4: Voltage input mode (-100 to +100 mV) (Display range -2000 to +2000)
5: Voltmetor display mode (-10V to + 10V) (Display range -10000 to +10000)
6: Amperemeter display mode (4mA to +20mA) (Display range 2000 to +20000 = 2mA to
20mA) if current is less than 2mA, a range error alarm will be set in BFM 28
7: Amperemeter display mode (-20mA to +20mA) (Display range -20000 to +20000)
