VSM Oven Software
6.1 Introduction
This document contains the following information:
○
Section 6.2 summarizes the
measurement process with the
Quantum Design VSM Oven option.
○
Section 6.4 describes MultiVu and the
VSM Oven-enabled software, focusing on
changes associated with the VSM Oven.
○
Section 6.3 describes some notable
changes to operations associated with
the VSM oven.
6.2 Using the VSM Oven for Measurements
The procedures for using the Quantum Design VSM in the oven mode are almost identical to
those for using it in the standard VSM mode. In fact, when you installed the VSM Oven software,
it was incorporated into MultiVu as part of the standard VSM software, so you will use the same
software to take measurements with the standard (low temperature) VSM and the VSM Oven.
Assuming that the VSM and VSM oven hardware and software have been installed, then each
time you use the
VSM Install/Remove Sample Wizard
, you will decide whether you will be
measuring with the standard VSM (low temperatures) or with the VSM oven. Other than that, the
same process is used for both types of measurements.
6.3 Changes Associated with the VSM Oven
6.3.1 Prevention of Overheating
To safeguard the equipment from overheating while it operates in oven mode, the cryostat sets
the coilset temperature to 295 K, and the VSM Oven software uses the VSM coilset temperature
as the primary diagnostic. In the event the VSM coilset temperature rises above 350 K, the
system shuts down the power to the oven heater.
