STAT:CHAN:ENAB 18 Programs the Channel Enable register to allow the occurrence
of either an OC or an OT condition to set the corresponding bit in the Channel Summary
Event register for the present channel.
STAT:CHAN:EVEN?;COND? Returns the values of the Event and Condition
registers for the present channel. The Condition value is the status as it existed at the
moment the Condition register was read.
CHAN 2;STAT:CHAN:ENAB 19 Programs the Channel Status Enable register to
enable OV, OC. and OT conditions to set the Channel Summary Event bit for Channel 2.

Description
The Channel Summary group of registers provides a convenient way to determine if any
enabled CHAN:STAT Events have occurred on a particular channel. The Channel
Summary group is primarily intended for use with multiple electronic loads. However, all
commands in this group are valid with single electronic loads. The following registers
comprise the Channel Summary group:
Event Indicates all channels on which an enabled STAT:CHAN
Register Event has occurred since the last time the register was read.
Enable Mask for selecting which bits in the Channel Event register
Register are allowed to be summed into the CSUM (Channel
Summary) bit of the Status Byte register.

Function
Returns the binary value of the Channel Summary
Event register. A 1 in the bit position indicates that
there is an event from that channel. Reading this
register resets it to zero.
A mask that specifies which bits of the Channel
Summary Event register can be selected to set the
Status Byte register CSUM bit. Set the bit to l to
enable the bit. Program MAX to enable all allowable
bits or MIN to disable them.
Returns the binary mask value of the Channel
Summary Enable register.
