4.0 Programs
4.1. Overview
A program allows the temperature and pump speed of the Optima to be controlled with time.
A program includes a global set of configurable alarms and a series of segments that are
executed in order. An unlimited number of programs can be created and saved on the PC
even if an Optima is not connected. However, the number and length of programs that can
be stored on the Optima is dependent on the model:
 GR150 – One program with upto 30 segments
 GP200 – Five programs each with upto 30 segments
 TX150 – One program with upto 30 segments
 TXF200 – 10 programs each with upto 100 segments
Segments are defined by a duration and a target temperature. These values can be used to
create “ramp”, “dwell” and “step” segments. Cooling “ramps” can be programmed but the
Optima must be used with a suitable refrigeration system to ensure the temperature can be
followed accurately.
4.2. Program editor window
The Program editor window allows programs to be created, saved and edited. It also allows
programs to be uploaded to the Optima and downloaded from the Optima. The Program
editor can be launched by selecting Programs from the main control window menu.
Labwise automatically detects the Optima model if one is connected. If an Optima is not
connected then the model you wish to create a program for should be selected.
