Steps to take with test equipment that has been idle to ensure accurate measurements.
June 9, 2020 - Vista, California -
Axiom Test Equipment,
an electronic test equipment rental and sales company has published a new blog
post entitled "Getting
Your Lab Equipment Back up and Running" that offers steps or precautions that should be taken with instruments that
have been idle for some time, which is not unusual during this time of the
COVID-19 pandemic, to ensure that they can provide the most accurate
measurements possible as you get back to work.
Since many of us have been
working only from home, projects requiring test equipment have been delayed and
the instruments in your lab have been left idle for a couple of months. Can
those instruments be expected to deliver the same levels of performance and
accuracy as soon as they are turned on? Axiom Test Equipment's latest blog post
delves into why it is best to take some quick and easy precautionary steps to
find out if your equipment is indeed within operating specifications and
therefore going to deliver accurate measurements.
For most companies, test
equipment represents a significant investment. Taking some time upfront to
perform preventative checks on your lab equipment is an efficient way to make
sure your work down the line is as accurate as possible.
Electronic test equipment is designed to deliver meaningful data concerning a
device under test (DUT), and most users assume they are achieving excellent
accuracy when they power up their instruments. But what if the test instruments
have been sitting on a shelf for some time (not unusual during this time of the
COVID-19 coronavirus pandemic)? Can those instruments be expected to deliver the
same levels of performance as instruments that are powered for use day after day
and perform regular measurement routines? Or should test instruments that are
being returned to regular use after considerable "downtime" be prepared in any
way for handling a regular workload once again? This blog post offers steps or
precautions that should be taken with instruments that have been idle to ensure
that they can provide the most accurate measurements possible.
Some instruments, such as digital multimeters (DMMs), are designed for
general-purpose, portable use and meant to be turned on and off as needed. There
is no "warm-up" time required. Similarly, portable analysis instruments such as
spectrum analyzers and digital storage oscilloscopes (DSOs) are designed to be
used shortly after being powered up and under a wide range of operating
conditions, such as operating temperature and relative humidity (RH). The same
is not true, however, for benchtop test instruments, such as signal or waveform
generators or vector network analyzers (VNAs) running on AC power. They provide
the most consistent performance after a certain amount of warm-up time and once
reaching a certain ambient temperature, surrounded by a nominal environmental
temperature of about +25°C or room temperature. The warm-up time may be only
one-half to one hour or even an amount of time specified in the owner's manual.
But without suitable warm-up time, a benchtop test instrument may not provide
the accuracy or repeatability specified in the owner's manual.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
