TELRAN 980437 Optical Multimeter
Overview
Handheld luminous power red pen all-in-one machine series product mainly used
for measuring to continue optical signal capacity and fibre-optical route
closed-open testing. It applies single chip microprocessor to carry out
control, and with completed function. It was widely used on optical cable
construction and maintenance, fibre- optical communication, optical cable
sensing, light CAT etc. areas. Machine body pattern design conforms to human
body engineering requirements, and it applies advanced cold molding
technology, it is beautiful and durable. Optical power meter red light pen
all-in-one machine applies built-in detector and laser, and it could make it
protected very well. All-in-one machine has delicate appearance, auto power
off , two kinds of red light mode, three kinds of backlight mode, wavelength
memory function, fibre-optical work identification, manual calibration, red
light with higher capacity, wide testing range.
Note: the version of the instruction is subject to change without notice.
Product characteristic
- Supporting linear(mW) and nonlinearity index (dB) displayed at the same time
- Supporting auto power off
- Supporting on/off background light
- Supporting customer self-alignment
- Supporting SC, FC interface, ST interface (apolegamy)
- Charging battery life work time is 48 hours (apolegamy)
- Supporting charger baby/computer power supply (apolegamy)
- Supporting memory wavelength function
- Supporting fibre-optical work identification
- Supporting red light normally flash and flicker
Technical index
Note:
- Range of wavelength: a standard working wavelength that we specified: 入 min-入max, the optical power meter within this range can work well with all indicators meeting requirements.
- Power measurement range: the maximum power that the meter can measure as per required indicators.
- Uncertainty: the error between the test results and standard test results over a standard optical power.
Press key description
-
Startup & Shutdown
It could start up immediately after pressing 1 second, and long press this key under startup status could shut down immediately. Startup default open auto power off function ( 10min), start up shortly press this key until power mark at the upper side of LCD disappeared, then close auto power off function. -
UNIT
Changing data display unit. It could select dBm, dB, nW unit accordingly, and test data will show corresponded result, conversion relationship of nW, dBm is: 10 log(nW)=0(dBm). -
REF
It could achieve automatic zero clearing to press this key, and set current test result as or confirmed as reference value, and carrying out relative power measurement, and display screen will show setting dBm value. -
入
It could select 6 types of different wavelength (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm), and it will show at LCD screen at the same time. -
LIGHT
Open/close red light, shortly press to start up or close, lower right hand of LCD displays 650 word typeface when opens it at the same time. -
GLINT
Under condition of red light startup, shortly press this key and red light is flicker, it will close after press it once again. -
Fiber-optical work identification function
Pressing “REF”+”UNIT “key to start up fiber-optical work identification, and identifies fiber-optical work frequency, then pressing it this combination key will be closed.
LCD display description
Measured power value will show with way of dB, dBm, mW, uW, nW, and display wavelength is 6 types and current work status etc. Background light switch
LCD POWER | GLINT+LIGHT | Display ☀, Switch backlight tips |

Calibration function description
Pressing λ”+“REF”+“UNIT” key at the same time, then enters user mode, and lower right corner of screen displayers letter “CAL”, and following functions are valid after pressing this combination key.
Function | Key | Remark |
---|---|---|
Increasing 0.05dB | REF | 1.01158 |
Reducing0.05dB | UNIT | 0.99855 |
Keep | Power key | Shortly press (Stored in flash) |
Switching wavelength | Enter | |
Restore factory settings | REF+UNIT | Displaying “FAC”, and reading the default |
value in array at the same time.
Note: Pressing “REF” and “UNIT” keys makes all-in-one machine at the same time and restore factory status.
Measurement to relative power and absolute power
-
Absolute power
If currently selected measurement wavelength is 1310nm, accessed the detected light, and the screen displays current value including linearity and nonlinearity of absolute light power. -
Relative power
After setting well wavelength, under absolute light power mode, accessed measuring light, and measured current power value, then press REF key once again at this moment, current power value will become single reference value (takes dBm as unit). It displays current absolute power value and current relative power value is 0dB at the moment, accessed another measuring light, displaying absolute light power value and relative light power value of current measuring light.
Standard configuration
The host machine, product warranty card, certificate, instructions, Oxford
roolls (apolegamy), three 5 dry cell batteries (apolegamy), adapter (SC and FC
standard, ST apolegamy).
Charging function
When it doesn’t display electric quantity index, and electric quantity is
insufficient to provide normal work when working, electric quantity index
flashes one time per 1 sec, and it will auto power off after 10 secs, please
don’t start up at that time, it should start up after charging with matched
power adapter.
Solutions to common faults
Malfunction Tips | Cause | Solution |
---|---|---|
LCD monitor weak | Insufficient power | Charge or change battery |
Could not display when starting | Lack of power or other | Restart machine or |
charge, change battery
Abnormal data display of LCD| Adapter fault, dirty or be locked| Reconnect
adapter and clean sensor
Red light weak| Insufficient power| Charge or change battery
Routine maintenance and maintenance
- Please keep cleaning of the sensor frequent and there should be no fat, no pollution and not use dirty and not standard adapter. Do not insert the end face of bad polished surface, or it will damage the end face and there will be error in testing.
- Stick to an adapter as much as possible.
- Once the machine is unused, please cover the dust cap to keep the end face clean prevent from exposing in the air and prevent from attaching the dust which leads to the wrong measurement.
- Carefully plug optical adapter connector to avoid port scratches.
- Clean the sensor surface periodically. When cleaning the sensor surface, wipe it gently in the circumferential direction with a special cleaning swab.
