Usage
value = dmm.limit[Y].low.value
dmm.limit[Y].low.value = value
value
The low limit value of limit Y; the valid range is -4294967295 to +4294967295
Y
Limit number 1 or 2
Details
This attribute is valid for all functions except "continuity" and "nofunction". A nil response
and an error are generated if the command is received when dmm.func is set to either of these
functions.
This command sets the lower limit for the limit Y test for the selected measure function. When limit Y
testing is enabled, this causes a fail indication to occur when the measurement value is less than this
value.
You may set or get the value regardless if the limit is set to a digital I/O trigger stimulus:
• dmm.trigger.EVENT_LIMIT1_HIGH
• dmm.trigger.EVENT_LIMIT1_LOW
• dmm.trigger.EVENT_LIMIT2_HIGH
• dmm.trigger.EVENT_LIMIT2_LOW
Example
This example enables limits 1 and 2 for DC volt, measurements. Limit 1 is checking for readings to be
between 3 and 5 volts while limit 2 is checking for the readings to be between 1 and 7 volts. The auto
clear feature is disabled, so if any reading is outside these limits, the corresponding fail will be 1
afterwards. Therefore, if any one of the fails is 1, analyze the reading buffer data to find out which
reading failed the limits.
