the instrument to be calibrated or signal to be measured. Each
time you turn on the PIECAL 820 the LCD displays the following
screen for about 1 second followed by operating in the function
used the last time it was operated.
Double Click the EZ-DIAL knob to change the function of the
calibrator and to select ranges, units and other user settings.
Each function (mA, V, T/C, Ohms, RTD, Frequency) has two
pages of menus. The first menu page has settings for the func-
tion and the second menu page has settings for STEPPING,
AUTO OFF and BACKLIGHT. Settings are remembered even
with the power off but are reset when the batteries are changed.
