Interface Operation
7 Interface Operation (METRAHIT AM XTRA / OUTDOOR /
SECULIFEHIT
AM/MD only)
The METRAHIT AM XTRA / OUTDOOR is equipped with an infrared inter-
face for the transmission of measurement data to a PC. Measured
data are optically transferred through the instrument housing by
means of infrared light to an interface adapter (accessory), which
is attached to the multimeter. The adapter’s USB interface allows
for the establishment of a connection to the PC via an interface
cable.
Beyond this, commands and parameters can be transmitted from
the PC to the multimeter as well. The following functions can be
executed:
• Configuration and read-out of measuring parameters
• Measuring function and measuring range selection
• Start measurements
• Read out stored measured values
7.1 Activating the Interface
The interface is automatically activated for receiving operation
(multimeter receives data from the PC) as soon as the interface is
addressed by the PC, assuming that the “irStb ” parameter has
been set to “ir on ” (see chapter 7.2), or the instrument is already
switched on (the first command wakes up the multimeter, but
does not yet execute any further commands).
The “continuous transmission” operating mode is selected
manually as described below. In this operating mode, the
instrument continuously transmits measurement data to the PC
via the interface adapter, which can then be displayed with the
help of a terminal program.
Starting Continuous Transmission Operation with Menu Functions
1nFo
... SEnd StArt send
The symbol blinks at the display in order to indicate interface
operation.
Stopping Continuous Transmission Operation with Menu Functions
1nFo
... SEnd send
stop send
The symbol is cleared from the display.
Automatic Activation and Deactivation of Transmission Mode Operation
If the sampling rate is 10 seconds or longer, the display is
switched off automatically between samples in order to prolong
battery service life. The only exception is when the multimeter is
set to continuous operation.
As soon as an event occurs, the display is automatically switched
back on.
