■GETTING STARTED AND TURNING ON

This and following sections show you how to use your instrument:

Check that the correct accessories have been supplied, and an optical connector adaptor has been fitted. If you have any queries, call your supplier to resolve the situation.

Put in the batteries, or plug external power into the socket at the top of the instrument (see Battery and External Power section).

Push the green POWER button. The display will come on. If the battery is low, this will be indicated on the display. Pushing POWER again will turn the instrument off.

To stop the instrument turning off 10 minutes after the last key press, hold POWER down for 3 seconds during turn-on. PERM on the display indicates that the unit will stay on permanently.

To back light the display temporarily, select LIGHT. To back light continuously, hold down the button for 3 seconds. Use of the back light will drain the batteries faster.

This instrument uses a menu driven keypad. The function of each button is shown on the display.

To access the optical connector, grasp a top corner of the instrument, and pull off the cover. The connector can be swivelled to improve access.

After instrument turn on, the instrument will perform a self- calibration sequence, set the dark current adjustment, and then display absolute power in dBm at the previously set λ. If HI or LO are displayed, the input is out of range.

The hidden keypad is accessed by pulling up the hinged display cover. The hidden keypad can operate in two modes. The second mode is accessed by SHIFT. Access to the second mode can be denied / permitted by typing the button sequence

:POWER (turn on instrument), SHIFT, CANCEL, SET, SELECT, RECALL, STORE.
