Safety/EMC
Safety: EN61010-1
(Out of conformance since December 1, 2010.)
EMC: EN61326-1 ClassB, Table2 (for use in
industrial locations)
1. Connector type. Specify FC, SC, LC, MU, or ST.
2. The user calibration function setting varies depending on the fixed
optical attenuator used.
3. Ta = 23 ± 5°C, at reference conditions (@ 1310 nm, -20 dBm).
Excluding when setting the user calibration function.
4. Do not remove the batteries or unplug the AC adapter during
operation.
5. By connecting to a PC on which the USB application software is
installed, saved data can be output in CSV format.
6. Measurement up to +30 dB is possible when using a 20 dB fixed
optical attenuator (that supports 1 W).
7. When connecting to the AQ2160-02, use a temperature range of
0–+50 °C. However, the safety standard for the AC adapter
specifies an operational temperature of 0–40°C.
8. With the optical input connector cap and DC connector cap
completely attached (without gaps).
9. When using USB, use a shielded USB cable of 2 meters in length or
less. Attach a ferrite core (TDK: ZCAT1325-0530A or equivalent)
on one end of the USB cable, close to the instrument’s USB
connector.
1-8. Periodic Calibration
Periodic calibration is an effective way to maintain the normal
functionality of the instrument over long periods of time, and to enable
quick identification of any problems. It is recommended to perform
calibration of the instrument once per year.
