7.3.1.2
Automatically Transmitting Measurements
By setting the sample period, the 1502A can be programmed to automatically
transmit measurements from the RS-232 port at specified intervals. The sample
period can be set remotely using the commands:
SA=[[hh:]mm:]ss
SA=0
The value of the sample period can be from 0 seconds to 24 hours. It is not nec-
essary to give hours or minutes for values in seconds. A value of 0 disables au-
tomatic transmission of measurements. Following are some example
commands.
SA=10
SA=5:00
SA=1:00:00
7.3.1.3
Selecting the Unit of Measurement
The selected unit is used in displaying measurements on the front panel and in
reading measurements from the communications interfaces. The following
commands can be used to select the unit of measurement:
U=C
U=F
U=K
U=O
7.3.1.4
Enabling the Time Stamp
Enabling the time stamp causes the time of the system clock to be transmitted
along with measurement data. The time stamp can be enabled or disabled using
the following commands:
ST=ON
ST=OFF
7.3.1.5
Setting the Clock
The system clock is set in 24-hour format using the command:
CL=hh:mm:ss
For example:
CL=14:24:00 sets the time to 2:24 pm.
