te107_control's Introduction

Python library for controlling TestEquity TE series Temperature Chambers

This is a library that (partially) implements the SCPI based interface of the Watlow controllers used by the TestEquity TE series of Environmental chamber.

Requirements:

Python 3+

This library only uses built-in python libraries.

Usage:

Install Python
Install Git
- Ensure to add git to your PATH if it is not already.
Install packaging scripts:
- sudo apt install python3-pip
- sudo apt install python3-venv
Clone this repository:
- git clone https://github.com/an-oreo/te107_control
Package and install:
- python3 -m build
- python3 -m pip install --break-system-packages dist/te107_control-0.0.1.tar.gz
In the file you intend to use this, ensure to import f4t_control

Example Usage:

from time import sleep
from f4t_control import (F4TController, RampScale, TempUnits)

# setup a temperature sweep
temp_units = TempUnits['C']
start = -40
stop = 125
step = 5
ramp_time_min = 3.0
soak_time_min = 7.0
temps = range(start,stop+step,step)

# instantiate the unit
x = F4TController(host='169.254.250.143',timeout=1)

# configure unit for sweeping temperature
x.set_ramp_time(ramp_time_min)
x.set_ramp_scale(RampScale.MINUTES)
# ensure chamber is enabled:
x.set_output(1,'ON')
# ensure units 
x.set_units(temp_units)

for temp in temps:
    print('ramping to temperature {}'.format(temp))
    x.set_temperature(temp)
    # wait for ramp time to finish
    sleep(ramp_time_min*60)
    while abs(x.get_temperature() - temp) > 0.2:
        sleep(1.0)
    # begin soak
    print('beginning soak at temp {}'.format(x.get_temperature()))
    sleep(soak_time_min*60)

# turn off unit
print('completed sweep!')
x.set_output(1,'OFF')
x.set_temperature(22)
# cleanup for socket connection is handled automatically
