Reference Key 

a.

 

Short press momentarily displays the current reference value  

b.

 

Long press (> 2 seconds) sets current Power Meter measurement as the reference level.  
Two beeps will sound when the reference level has been set and will display dB units. 
When the reference value is set, it is only applied to the current wavelength.  Individual 
reference values for each wavelength can be set and stored separately.  After a reference 
value has been set and each time the wavelength is selected on the power meter, the 
measurement will use the correct reference offset automatically. The offset is shown in 
dB.  To get the absolute power measurement, press the dBm/dB/mW key until the 
measurement in dBm is shown. 
Note: Deleting all of the stored values will not delete the reference measurements.

Power key 

a.

 

Short press until beep sounds to power on with auto-off function Active 

b.

 

Long press (>2 Seconds after beep) when powering on Disables auto-off function 

c.

 

Meter will display “auto-off” when function is enabled. 

 

10.

 

Unit of Measure selector key 

a.

 

Press to cycle between dBm, dB and mW.  dBm units will always display the absolute 
measurement value.  dB units will show the delta between the absolute measured value 
and the stored reference level.  For example:  The measured power value is 5 dBm.  The 
Reference value has been set to 4 dBm.  The delta between the measured value and the 
reference level will be 1dB. 

b.

 

In “Load” mode, this key will function as the up arrow key to numerically cycle through 
stored measurements:  1, 2, 3 … 

11.

 

Backlight key 

a.

 

Press to cycle display backlight on and off 

b.

 

In “Load” mode, this key will function as the down arrow key to numerically cycle 
through stored measurements:  3, 2, 1 …
