If the data logging function is used with a computer, the computer must be either
continuously waiting for data or serial polling the GPIB interface to test whether the meter is
trying to send data.
To deactivate the data logging function:
1. Set the power switch to
O (off).
2. Turn the power switch to
I (on).
3. Select the Initialize option during power-up; or repeat the preceding procedure, selecting
OFF rather than ON in step 2.
Setup Using a Reference Reflector
In ordinary use, the Setup function enables the front-panel detector to measure the connector
loss of the measurement jumper. The Setup function adds an offset to the backreflection
readings to compensate for this loss.
For a device with a known backreflection, the function of the SETUP key can be changed:
1. Press the MENU key.
2. Press the soft key labeled MORE MENUS.
3. Press the soft key labeled SETUP MENU.
4. Press the soft key labeled SETUP VIA: LOSS to set the status option to REFLECTION.
5. Press the soft key corresponding to the required wavelength.
6. Press
the or key to adjust the reference reflection.
7. Press the POWER or BR key to exit Menu mode.
8. Attach the reference reflector to the output of the jumper.
9. Press the SETUP key. The meter measures the backreflection of the reference reflector.
The meter assumes that the difference between the reading and the value stored in step 6 is
caused by loss, and adjusts the offset to compensate for that loss in future measurements.
10. To have the meter perform the setup for both wavelengths, hold down the SETUP key for
more than two seconds.
If the key lamp is already lit, pressing the SETUP key turns off the key lamp and restores the
standard offset of 0.3 dB.
To reset the meter to SETUP VIA: LOSS:
1. Set the power switch to
O (off).
