Traveling Standards - Protocol

Carefully unpack the Traveling Standard (TS).

Shipping package contents include:

1. The Traveling Standard (in a 2" x 7" PVC pipe)
2. Wall wart power supply (24 Vdc @ .25 A)
3. TS schematic
4. These notes
5. Bubble bags for the TS and the PS.

Locate and save the return pre-addressed postage paid shipping package.

Avoid RF fields (cell phones, wifi, walkie talkies, ...)
To the extent possible maintain measurement environment at constant temperature.
Make sure all measurement instruments are warmed up.
Measurement instruments input impedance should be at least 10 Megohms.
Note any recent calibrations of all measurement instruments.
Plug in the TS and note the time it is powered up.
Let the TS warm up for at least one hour.

To avoid ground loops, make only one measurement at a time with the other two banana jack pairs open circuited.

For each measurement record the following:

Date and time
Room temperature
Measurement instrument used (make and model number)
LM35 reading (white(+) / black(-) banana jack pair) to at least three places (0.1 degree C).
MAX6350 (5 Volt) reading (blue (+) / black (-) banana jack pair) to highest resolution.
LM119AH (7 Volt) reading (red (+) / black (-) banana jack pair) to highest resolution.

Repeat measurements as you have time to.

If you have time or the desire to, record average readings noting the number of samples averaged and any other useful information.

Leave TS powered up continuously until measurements are completed.

Make the last measurement at least 24 hours after the TS was powered up.

Carefully repack the TS in the return package. Call FedEx to schedule a pickup or drop it at a FedEx drop box or store.

THANKS!
