Getting Started
Model 235 Software is not difficult to use, but like many application that use RS-
232 serial port communications it all goes smoother if you follow some basic
steps in the same order when starting. The following steps will guide you through
this procedure. The steps are presented twice: First the overview of the procedure
in high level steps, Second is the detailed steps presentation and all sub-steps to
get started. If this is the first time you have setup and operated the Model 235
Utility software or you are encountering difficulties we recommend reading the
detailed steps to avoid omitting anything in the procedure. After that the Quick
Steps will serve as a handy reminder.
Quick Steps:
1) Connect the Model 235 to the PC COM Port, Select the test parameter and
range, connect the test leads to the circuit to obtain desired LCD reading and
press the RS232 menu button.
2) At the PC, open the Model 235 Utility and use the Set Up then
“Communications” command to initiate the COM port communications.
3) Note the PC monitor screen and Model 235’s LCD reading agree and select
desired monitoring, recording, storing or printing feature.
Once started. the Model 235 selector switch and test leads can be changed to
measure any parameter and the PC will shift to that parameter and range.
Detailed Steps:
1) Connect the Model 235 DMM to the PC using the optically isolated serial
cable provided. Not all serial cables are alike in wiring and pin out, so we
recommend using only the supplied cable with p/n 1000-1495-01.
2) At the Model 235, rotate the range switch to the desired parameter and range
for the measurement. Some functions are autoranging while others require a
range selection or AC/DC selection. See the General Instructions for complete
details on each function and precautions.
3) Connect the test leads to the circuit/component to be tested and note LCD
reading. Make any range or connection adjustments necessary to obtain the
best reading and resolution.
4) Press the RS232 menu button to activate the serial port output. For extended
recording periods, the Auto Power Off feature may be disabled. See Auto
Power Off section on page 26 of Operator’s Manual.
5) At the PC, open the Model 235 Software by double-clicking on the icon in the
Wavetek directory, Meteman directory, or file folder.
