Description of the parameter current_source_value_x (x = 1...4):
With this parameter the measuring current can be selected individually for each channel.
For measuring resistors up to approximately 500
J
resistance the measuring current can be 400
K
A.
For higher values the self-heating of the sensors should be noted and if necessary the lower
measuring current has to be selected.
If the lower measuring current is selected, the parameter ADC_PGA_x (object 2400
h
) has to be set to
“4” (for information about the selection of measuring current and measuring resistance please refer
to page 100).
Value range:
current_source_value_x = 0 : measuring current = ca. 400
K
A
current_source_value_x = 1 : measuring current = ca. 40
