UNCAL when the peak-to-peak input voltage is
greater than three times the RMS AC range
selected.
DC—Measures dc voltage from 0 to 500 V in three
ranges.
A T IM E —Disconnects the DMM from the LCD
readout and allows the instrument to display a
digital readout of time difference between any two
points on the oscilloscope display.
The maximum safe inp ut voltage is 500 V (dc +
peak ac) between the + (positive) and
—
(negative)
inputs o r between the + and — inputs to ground.
(40) DMM INPUT Connectors—Two banana jacks provide
positive (red) and negative (black) inputs fo r voltage
and resistance measurements.
(4?) Readout-Consists o f a 3 1/2-digit LCD unit which is
used to display measurements selected by the
RANGE/FUNCTION switch. No polarity indication
is displayed fo r positive values. Negative polarity
indication is automatic for negative values. Decimal
point indication is automatic. In an overrange con­
dition, a " 1 " w ill be displayed on the left side o f the
LCD readout, followed by three blank digits and a
decimal point.
REAR PANEL
Refer to Figure 8 fo r location o f items 42 and 43.
(42) GND Connector—Provides direct connection to
instrument chassis ground.

) EXT Z AXIS INPUT Connector-Provides a means of
connecting external signals to the Z-Axis amplifier
to intensity modulate the crt display. Applied signals
do not affect display waveshape. Signals w ith fast
rise time and fall time provide the most abrupt
intensity change.
Positive-going signals decrease
the intensity, and a 5-V p-p signal w ill produce
noticeable modulation. Z-axis signals must be time-
related to the display to obtain a stable presentation
on the crt.
