Operating the Meter Using the Computer Interface

5

Preparing the Meter for Operations via the RS-232 Interface

RS-232 Print-Only Mode

The print-only mode is intended to be used primarily in those cases where you want to send measurements taken by the meter to a printer or terminal automatically.

While the meter will respond to remote commands during "print-only" operations, we recommend first setting the meter’s echo mode to "OFF" (see above). This will prevent mixing echoed command characters and incoming data.

In the print-only mode, the meter sends every Nth reading shown on the primary and/ or secondary displays out the RS-232 port. The print rate (N) is selected by the user from the available values for N. provided in Table 5-2. The duration between output is determined by the reading rate of the meter (slow (2.5), medium (5.0), or fast (13.5) and the print-only rate. The output is formatted as one measurement per line from the primary display or two measurements per line from the primary and secondary display.

Perform the following procedure to select the print-only mode and set a printing rate (N):

1.Press in the POWER button on the front panel to turn the meter on.

2.Press S, then press J(ADDR).

If the RS-232 interface is selected, "PRINT" is shown in the secondary display and the list editor is invoked on the print rate list.

3.Press Uor Tto scroll to one of the print rates shown in Table 5-2, then press Eto select that rate. A print rate of "0" disables the print-only mode.
