5-16.Measuring AC and DC Signals
The Meter is capable of displaying both AC and DC signal components (voltage or current)
as two separate readings or one AC+DC(RMS) value combined. As shown in Figure , the
Meter displays ac and dc combinations two ways: DC displayed over AC (DC,AC), and AC
combined with dc (AC+DC). Select one of these three displays using the Function and Mode
menu. With the rotary switch set to V, mV, A, mA,or uA, press the soft key labeled Menu.
Move the menu selector to the menu item labeled AC+DC. At this point, three different soft key
labels indicate AC+DC (F1),and DC,AC (F2). Press the soft key that presents these two
signals as needed. While in any of the three AC+DC modes, peak measurements, frequency,
duty cycle, relative %, and period measurements are not allowed. In addition to these modes,
MIN MAX, relative.
5-17.Capturing Minimum and Maximum Values
The MAX MIN Record mode captures minimum, average, and maximum input values. When the
input goes below the recorded minimum value or above the recorded maximum value, the
Meter beeps and records the new value. The Meter stores the elapsed time since the recording
session was started at the same time. The MAX MIN mode also calculates an average of all
readings taken since the MAX MIN mode was activated. This mode is for capturing intermittent
readings,recording minimum and maximum readings unattended, or recording readings while
equipment operation precludes watching the Meter. The MIN MAX mode is best for recording
power supply surges, inrush currents, and finding intermittent failures. Response time is the
length of time an input must stayat a new value to be captured as a possible new minimumor
maximum value.
To activate the MAX MIN mode, press MAX MIN. As shown in Figure, the Meter displays e
at the top of the measurement page, and the MAX MIN start date and time along the bottom of the
page. In addition, the recorded maximum, average, and minimum values appear in the secondary
display with their respective elapsed times.
To stop a MIN MAX recording session, press
the softkey labeled Stop. The summary
information in the display freezes, and the
softkeys change function to allow saving
the collected data. Pressing the softkey
labeled Close exits the MIN MAX record
session without saving the collected data.
