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 sets the sample period

SA=0 disables automatic transmission of measurements

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 sets the sample period to 10 seconds

SA=5:00 sets the sample period to 5 minutes

SA=1:00:00 sets the sample period to 1 hour

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 selects Celsius

U=F selects Fahrenheit

U=K selects Kelvin

U=O selects ohms

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 enables the time stamp

ST=OFF disables the time stamp

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.
