4. Rechargeable Li-battery instead of dry battery
T20 Portable optical power meter is an accurate and durable handheld meter designed for the installation, operation and maintenance of optical fibre network. It is a compact device with backlight switch and auto power on-off ability. Besides, it provides ultra-wide measurement range, high accuracy, user self-calibration function and universal port. In addition, it displays linear indicators (mW) and non-linear indicators (dBm) in one screen at the same time.
Features:
1. Self calibration by user himself
2. Rechargeable lithium battery supports continuous work for up to 48 hours.
3. Linear indicators (mW) and non-linear indicators (dBm) display in one screen
4. Unique FC/SC/ST universal port (see Figures 1, 2), no complex conversion
5. Optional auto power-off ability
6. Backlight ON/OFF
