R Recording Measurements

Recording Measurements

Press Rto begin recording readings for all measurement functions. Then press <or >to cycle through the screens for the function presently selected. You can also switch between measurement functions while in Record mode. (See Figure 16 for an overview of possible record screens.) For any function, the Tester displays screens in the following order:

•NOW The present readings. This screen always appears first when you start Record.

•MAX The maximum values measured since you started Record.

•AVG The averages of values measured since you started

Record. (Average values stop updating after 48 hours of continuous record operation.)

•MIN The minimum values measured since you started Record. WhenE<>in ecord, only the following keys are active:C

F

Press Ra second time to exit Record. This action discards all recorded values and returns to the previous measurement screen. The Tester begins storing a new set of values each time you start Record.

The Tester loses recorded values if the batteries discharge too much. If b comes on during Record, write down any values of interest. (You have ample time to do this with alkaline batteries. NiCad batteries discharge much more rapidly once bcomes on.) Changing the battery erases the Record memory.

You can access 12 different record screens: NOW, MAX, AVG, and MIN for volts, amps, and watts measurement functions. Figure 16 presents an overview of the record measurements and computations available by function.

Note

The Record mode acquires only single-phase data approximately every 500 ms (0.5s). It is not intended to capture transients, nor is it able to capture single events on the power line.
