value
The high value for limit Y; 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 attribute specifies or queries the high limit value of limit Y. When limit Y testing is enabled
(dmm.limit[Y].enable = 1), a fail indication occurs when the measurement value is greater than
this value.
You may set or get the value regardless if the limit is set to a digio 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.
