Main Macro Commands:

Goto

Free length
Home
Initial tension
Length
Load
Graph Length/Load

Finds the free length of the spring.
Goes back to the home position.
Finds the initial tension in an extension spring.
Goes to an absolute length.
Goes to an absolute load.
Enables test points on graph to be selected.

Graph

Length/Load Hysteresis

Produces a load up/load down deflection graph by compressing the spring to a given length.

Move by

In addition to the above commands there are:

Set commands

Units, Machine type, Max speed, Max Length, Home.

Conditional and Loop statements for

IF, <, >, =, Goto line, Loop, Repeat.

Passwords

For protecting macros, data and machine calibration

Variable and mathematical operators

+, -, x, ÷

Delay and pause

Add time delays or stops

Label printing commands

Produces individual result labels for each spring.

RS232 I/O

Receive or transmit data via RS232

Genies:
To make programming simple we include Genies to help write the code. These include Initial tension, Spring rate, Load deflection graphs, Prestress, Permanent set and spring Hysteresis.

PC minimum requirements:
