Fig.3. The polarity of jackplug of cable for synchronization. Note! Without synchronization the amplifier readings can’t be true. 3. If necessary with the help of a cable connect the “Output” (7) of AMT-07M with recording instrument (for example oscilloscope or analog-to-binary converter). Figure 4. - Page 8 5. Using the button “Display mode” (8) select the PD temperature indication mode. The green LED indicator “T ” (12) will be turned on. On the LC measure display you can see (2) the real temperature of the PD’s chip. Fig.6.

The green LED indicator “Signal” (9) will be turned on. Fig.9. The button of display mode selection. The LED indicator of the signal level indication mode.
- Page 10 “ZERO” mode description. The intrinsic function for background level compensation (“ZERO” mode) is used for amplification and measuring the difference between the current signal level and the signal taken for the zero level. Using the start/stop button “ZERO ON/OFF” (10) this mode can be switched. The appropriate green LED indicator will be turned and the current signal is taken for the zero level in power up time.
