Tenma multimeter RS-232 software FUBAR


I purchased a Tenma 72-6870 multimeter from MCM (an inone company)
because it was cheap and it included an RS-232 output for recording
measurements.

My laptop is running Windows 98.

I installed the Windows 98 software from the CD included with the
multimeter.

The installation went well and I can start the application.

However, when I click on the on-screen "begin" button, I get a very
un-infoprmative error message "File is corrupt!" and nothing else.

The manual that came with the multimeter makes no mention of ANY error
conditions much less what to do about them. The manual appears to be an English
translation of an Estonian translation from the original Egyptian hieroglyphics
that it was written in.

The Tenma web site was of no help.

The MCM web site also has no customer support for technical problems.

Has anyone here used that multimeter with the RS-232 link?
