Python module for reading from the serial interface on the TekPower TP4000ZC multimeter and probably many others (supposedly this is the same as the VC820 module in QtDMM). This provides a very easy way to write software to take readings off the meter (and just running it will provide useful data).
This module requires the PySerial module.
Example Code:
# load the module
import tp4000zc
# the port that we're going to use. This can be a number or device name.
# on linux or posix systems this will look like /dev/tty2 or /dev/ttyUSB0
# on windows this will look something like COM3
port = '/dev/ttyUSB0'
# get an instance of the class
dmm = tp4000zc.Dmm(port)
# read a value
val = dmm.read()
print val.text # print the text representation of the value
# something like: -4.9 millivolts DC
print val.numericVal # and the numeric value
# ie: -0.0048
# recycle the serial port
dmm.close()
The module itself has full documentation. The protocol is described in the module but is taken from this image.
