4.6.2 THE MEASURING FUNCTIONS
1.
Anytime during the course of measurement, the serial and/or
parallel (i.e., printer) transmission can be activated.
In order to activate the transmission, make the appropriate
connection to the PRINTER or RS232 device. Refer to section
4.13. for more details.
Press
the
function key to initiate the transmission. If the
instrument establishes proper communication with the external
device (i.e., printer),
DATA
will be printed.
Improper communication will prompt an error message!
2.
If the timed data transmission has been activated, measured data
will be sent to the external device at the set time interval. Please
refer to section 4.11 for information on timed data transmission.
3.
The
START
or
STOP
inputs respond to a change of state. This
change may be a dry contact opening or closure, or the initial
application of an AC or DC voltage. The input terminals are
isolated from the chassis ground and are independent of signal
polarity.
4.
To save the measurements press the
SAVE
function key.
Pressing this key will TAG NUMBER the sub-screen. This number
is tagged to the saved data, for future reference. All saved data are
time and date stamped.

To change the measurement mode to
AVERAGE
, press the Volt
function key to toggle from
RMS
to
AVG
.
NOTE: When measuring DC volts, the instrument must be in
the RMS measurement mode only and positive
polarity connected to V
A
, V
B
, or V
C
!
6.
The instrument defaults to automatic ranging. If manual ranging is
desired, the unit must be in High Speed Capture or Timer mode.
Proceed as follows:
-
Press
HIGH SPEED CAPR
function key. Press the
CHANGE I & V RANGE
function key.
-
Press
CHANGE I RNG
