Item | Field | Description |
|
|
|
A | Battery status indicator | Displays the approximate remaining battery life. Three bars indicate the charge |
|
| level. When the battery indicator flashes, the batteries should be changed |
|
| immediately. |
B | REF indicator | Press the Ref/Set button to toggle through stored reference values. The reference |
|
| values for the currently selected wavelengths are briefly displayed in the following |
|
| order: |
|
| CW mode: The reference value is displayed in field E. |
|
| Single WAVE ID mode: The reference value is displayed in field E. |
|
| Dual WAVE ID mode: The reference values are displayed in fields E and G. |
|
|
|
C | WAVE ID indicator | Lights when a wavelength has been identified using the WAVE ID feature with a |
|
| compatible light source. |
D | Wavelength | CW mode: Displays the currently selected wavelength. |
|
| Single WAVE ID mode: Displays the detected WAVE ID wavelength. |
|
| Dual WAVE ID mode: Displays the first detected WAVE ID wavelength. |
E | Power | Displays measured power (dBm or μW), or insertion loss (dB) at the wavelength |
|
| displayed in field D. |
|
| If power or loss is too high or too low for accurate measurement, this field |
|
| displays HI or LO. |
|
|
|
F | Tone / Wavelength | CW mode: Displays detected tone modulation frequency. |
|
| Dual WAVE ID mode: Displays the second detected WAVE ID wavelength. |
|
|
|
G | Power | Displays measured power (dBm or μW), or insertion loss (dB) at the wavelength |
| (Dual WAVE ID mode | displayed in field F. |
| only) | If power or loss is too high or too low for accurate measurement, this field |
|
| displays HI or LO. |
