After the computer is connected, pressing any key ONCE! (while the H-3521 is in sleep mode)
will cause the H-3521 to wake up, make a new measurement and print the following message:
Stage = +/-X.XX
Temp = +/-XX.X
When the ENTER key is pressed after the H-3521 is awake it will invoke the H-3521 Simple
Menu. You will see a “Measuring...” message displayed as the H-3521 makes a fresh
measurement. Then the H-3521 will display the Simple Menu as shown on the following page.
