METEROFF/METERON
The METERON/METEROFF commands allow a macro to start or stop a metering channel from converting the
analog value into a digital value. This is useful when a calculated value needs to be displayed in a monitoring
view. When given the command of Meteroff, the meter channel will not display analog readings taken from the
input. A value can now be entered by using meterAD(x) or meterF(x) statements.
Either statement is followed by the metering channel number to be turned on or off inside of parentheses.

MACRO EXAMPLES
The following pages contain several examples of typical macros. For additional macro examples or further
assistance, visit the support section of the Burk Technology web site at www.burk.com.
Power Change
This example shows a power change and a limit change. First,
the macro mutes Meter Channel 2 to prevent any alarms that
might be triggered before the new limits are established. The
macro issues three commands to initiate the power change.
Then the macro sets new limits for Meter Channel 2. The 2nd
Lower Limit is set to 7 and the 1st Lower Limit is set to 7.4. The
1st Upper Limit is set to 7.6 and the 2nd Upper Limit is set to
8. The macro also sets new upper and lower limits for Meter
Channel 3 but does not mute the channel. After all adjustments
are completed, the macro unmutes Meter Channel 2 and ends.
While Delay
This example shows how a While statement can set up a variable
loop which pauses a macro until a defined set of conditions are
met. First, the macro mutes Status Channel 11, then issues
Command 13a. The While statement checks the reading of
Status Channel 11. As long as Status Channel 11 is “High,” the
macro will continue to loop and check the status. When Status
Channel 11 is no longer High, the While statement ends and
the macro issues Command 13b. Last, the macro unmutes
Status Channel 11 and ends.
