in this example, the cal bars are being measured for the very first time.
Therefore, all the readings are currently being stored in column A bolt
numbers 1 &2.
Now that the probe zero cal bars have been measured and documented, it’s
finally time to calculate the zero value. The following section outlines the
procedures for the zero value calculation.
Calculating the Probe Zero Value
1) Press the MENU key once to activate the menu items tab. Press the
MENU key multiple times to tab right, and the ESC key multiple times to
tab left, until the CAL menu is highlighted and displaying the submenu
items.
2) Use the UP and DOWN arrow keys to scroll through the sub menu
items until MEASURE ZERO is highlighted.
3) Press the ENTER key to display the new Two Point Zero List Box.
4) Use the UP and DOWN arrow keys to scroll through the list menu items
until CALC ZERO is highlighted.
5) Press the ENTER key to calculate the probe zero. The probe zero delay
value is now displayed in the Zero Value field.
This next section demonstrates how to go back and verify if the probe zero value
is still linear and “In Spec” at a later time. It’s important to note that user should
never have to change or re-calculate the probe zero value again, unless the
MINI-MAX, transducer, or cable has been replaced. If the transducer or cable
has changed, and the probe zero value re-calculated, the change in the zero
