Photocurrent input from the photodiode will be negative with respect to the amplifier. *3: If not using the AC adapter that comes with C9051, set the power supply voltage within this range. A separate adapter plug will be required for power input to C9051. *4: This is the maximum ripple allowed for the power supply when operated with all loads listed on the power supply specification sheet, excluding switching noise that might appear superimposed on the ripple. When not using the AC adapter that comes with C9051, always make sure that the power supply output does not contain excessive ripple and noise. ■Usable photodiodes Any single-element photodiode with a terminal capacitance below 15 nF can be used. In photometric applications requiring high accuracy, we recommend using metal package or ceramic package photodiodes. For detailed information refer to individual data sheets for our photodiodes. NOTE) C9051 cannot be used with multi-element photodiodes, photodiodes with preamplifier, APD (avalanche photodiodes), photo IC diodes and reverse-biased photodiodes.

The cable length (capacitance) should be less than 15 nF including photodiode terminal capacitance. • Solder the photodiode leads to connect the tip of the cable wire. (See the drawing on the right.) Anode: Connect to the shield wire of the cable. (Make electrical connection with the shield.) Cathode: Connect to the core wire of the cable. • To improve measurement accuracy, provide a shield around the photodiode. Do not use a cable any longer than necessary. (Keep the cable as short as possible.)

Otherwise, signal current cannot be drawn when the photodiode package is grounded.
