1. Summary KI6501 is an easy and economical handheld CWDM Power Meter for testing multi-λ single mode fiber optic systems. It scans and stores the absolute or relative power levels of all 18 CWDM λ in 0.8 seconds. Test data can be viewed in graphical or numerical form, and reference values can be stored for easy loss testing.
2. Main Instrument Features • Compact, rugged & light weight • Simple to use • Fast measurement speed • Scan range of 18 calibrated wavelengths • Larger, sunlight readable, backlit colour display • Simultaneous 9 wavelengths loss display • Tabular and graphical display modes •...
4. Safety Take appropriate eye-safe precautions when handling live fibre. Avoid condensation The instrument is resistant to normal dust and moisture, however it is not waterproof. If moisture gets into the instrument, remove the batteries and dry it out carefully for at least one hour before using it again. Storage The equipment can be stored at the specified temperatures and relative humidity.
6.2 Switching Instrument ON/OFF To switch ON instrument, press and hold [Backlight] for 2 seconds. The instrument will be defaulted to PM Auto (Auto Power Meter) Mode upon initialization; see pictures below for instrument displays. Time Battery charge indicator Date KI 6501 Initializing When the instrument is switched ON, its LCD backlight can be toggled ON...
KI 6501 Powering down 6.3 PM (Power Meter) Mode Power Meter can be operated either in PM Auto Mode or PM Manual Mode. PM Manual mode displays real time power measurement values. PM Auto Mode: In this operation mode, the instrument automatically scans the optical input and displays the wavelength (along with its corresponding measured power value) which has been detected with the highest level of power.
Page 11
PM Auto Mode PM Manual Mode: Use this operation mode to manually select and display real time power values of the wavelengths available at the optical input. See picture below for user interface of this mode. PM Manual Mode In PM auto Mode, press [PM] once to switch to PM Manual Mode. Use [▲, ▼] to select the desired wavelengths for power values displays.
6.4 CWDM Mode Press [CWDM] to scan optical input once and display power values in single-wavelength display mode. See picture below for CWDM user interface. Use [▲, ▼] to display the power values of other wavelengths scanned at the optical input. 6.5 SCAN Mode When [SCAN] is pressed, the wavelengths and their corresponding power values scanned at the optical input will be displayed in multiple-...
6.6 Measurement unit (dB/dBm) selection Press [dB/dBm] to toggle between the measurements units of dB and dBm in PM (Power Meter) Modes. The displayed power will be become “0.00 dB” when [dB/dBm] is pressed; see figure below. Revision: 4 Date: 18 Jun 2020 Page 13 of 28...
6.7 Graphical Display Mode Press [Graph] to display the wavelengths/power values scanned at the optical input in graphical format, see picture below for an example. Press [Graph] again will switch the display to the multiple-wavelength format shown in example of section 6.5. 6.8 Saving Scanned Data in Instrument’s Memory In SCAN Mode, press [Save] to save the scanned optical input data into memory, see below user interface.
6.9 Retrieving Data Save in Instrument Press [Recall] and the user interface below will be displayed. Use [▲, ▼] to highlight the desired file (in which data was saved) followed by pressing [ENTER]. The data will be retrieved and displayed on LCD as shown in picture below.
Use [▲, ▼] to scroll between the available displays pages to read all data in the retrieved file. Toggle [Graph] to display the retrieved data in graphical or tabular (multiple-wavelength) format. 6.10 Instrument Setup options Press [Menu] to display the available instrument setup options in the Menu Option List.
