only be exposed to unusual voltages for short and limited
time periods. If the input voltage is over 600 V, the meter will
be damaged.
mA Current Fuse Range: 250 V, 1A
If the current is over the rated range, the fuse will melt in
order to protect the meter. Replace a fuse only with a similar
rating. Open the battery cover to replace the fuse.
The 10 A socket is not equipped with a fuse to protect
the device with over range currents. Using the 10 A
socket to measure voltage will damage the meter.
2.3.26. Optical Power Meter (Optional)
Click and enter one of five wavelength, as follows: 1625 nm,
1550 nm, 1490 nm, 1310 nm, 1300 nm, or 850 nm.
Linear or nonlinear optical power displays are available for optical
power testing and fiber link loss relative measurement. This is a
useful tool for the installation and maintenance of optical fiber
communication, cable television, and security systems.
Keep the fiber connector and the dust cap clean, and
clean the detector with special alcohol.
Data Hold
While testing, click Hold to hold data. Held data will not change and
