3.2 Creating a Standard Log (cont.)
Refer to Chapter 3 of the Service Manual for a discussion of the many parameters accessible via the DIAG option.
Note: The units assigned to the parameters in Table 35 on page 66 are those selected in the User Program
(SYSTM submenu).
6. Use the [
, [ and [F1]-[F4] keys to select the second parameter to be logged. See Table 35 on page 66 for a
list of the available options.
7. Use the [
, [ and [F1]-[F4] keys to select the third parameter to be logged. See Table 35 on page 66 for a list
of the available options.
• If you selected a totalized value for display, go to step 8.
• If you did not, go to step 9.
8. At the Set LOG Totals to 0? prompt, press [F1] to leave the log totals at their present value or press [F2] to reset
the log totals to zero.
Note: The Set LOG Totals to 0? prompt only appears if either +TOTL or -TOTL was selected as one of the three
parameters to log. Choosing YES at this prompt only resets the log totals to zero and has no effect on the
meter totals.
3.2.1 Log Type
9. Press [F1] to create a non-circular log or press [F2] to create a circular log.
A non-circular log automatically stops when the meter runs out of memory or the specified END TIME is reached. A
circular log runs continuously until manually stopped, but only the data from the most recent log cycle is saved. At
the start of each cycle, the oldest recorded data is overwritten by the new data from the current cycle.
CAUTION! If data from one circular log cycle exceeds the meter’s memory capacity, the earliest logged data will
be lost.
3.2.2 STARTTIME Prompt
10. Press [F1] to accept the displayed Start Time or press [F2] to enter a different start time. To start logging
immediately, press [F3].
• If OK was selected, proceed to step 11.
• If NOW was selected, proceed to step 12 if you selected a non-circular log or to step 14 for a circular log.
• If EDIT was selected, complete the steps listed below.

Press [F1]-[F2] to select AM or PM. Then, enter the desired Hour (1-12) and press [ENT]. (Entry of a start time earlier
than the current time will generate an error message.)
