TCP305 and TCP312 DC Gain Adjustment
Use the following procedure to adjust the DC Gain of the TCP305 and TCP312
Probes.
1. Connect the amplifier OUTPUT to the DMM input using a BNC-to-Dual
Banana connector, 50 Ω BNC cable, and a 50 Ω precision feedthrough
termination. Do not connect the termination at the amplifier output.
2. Connect the current probe to the amplifier PROBE INPUT connector.
3. Connect the 5-turn DC current loop to the current source as shown in
Figure 6--4 on page 6--9.
4. Do not clamp the current probe around any conductor, but make sure the
slide is locked.
Make or verify the equipment settings in Table 6--6:
