MATHEMATICAL STATEMENTS

The macro program has a wide range of mathematical

statements that may be used to achieve your desired outcome.

Each statement will use standard notation with parentheses

being used to define a computational hierarchy. Some standard

trigonometric operators may be used as well.

Numerical results of mathematical computations are not always

exact. For example, -4 would not come back as 2. It would come

back as 1.9999 or 2.0001. Take this into consideration when

using mathematical statements in any macro.

A list of supported mathematical statements is available on the

table on page 120.

Macro Line Example Description

If meter(3)>50 Then [CR] Compares Meter Channel 3 of this unit to the value of 50.

End [CR] If Meter Channel 3 is GREATER THAN 50, the macro ends.

Else [CR] If Meter Channel 3 is NOT GREATER THAN 50, then issue

Command ME, ME, 1A [CR] command 1A on this unit.

ENDIF [CR]

> GREATER THAN

< LESS THAN

Macro Line Example Description

If meter(3)<50 Then [CR] Compares Meter Channel 3 of this unit to the value of 50.

End [CR] If Meter Channel 3 is LESS THAN 50, the macro ends.

Else [CR] If Meter Channel 3 is NOT LESS THAN 50, then issue

Command ME, ME, 1A [CR] command 1A on this unit.

ENDIF [CR]

< > NOT EQUAL TO

Macro Line Example Description

If meter(3)<>50 Then [CR] Compares Meter Channel 3 of this unit to the value of 50.

End [CR] If Meter Channel 3 is NOT EQUAL TO 50, the macro ends.

Else [CR] If Meter Channel 3 is EQUAL TO 50, then issue command

Command ME, ME, 1A [CR] 1A on this unit.

ENDIF [CR]
