Teledyne 200AH 用户手册

 

Due to the stability of modern electronics, this procedure should only need to be performed if a 
major sub-assembly is exchanged or when the display voltage does not match the input voltage 
or current to the V/F card. After completion, a Factory Calibration Procedure should be 
performed, see Section 9.1.6. 

Before the actual calibration is performed, switches on the V/F card must be correctly set and 
jumpers set on the motherboard. Jumper and switch setting changes must be performed with 
the instrument power OFF.  

Motherboard Jumpers 

The motherboard contains 4 pairs of jumpers JP1 - JP8, one pair for each analog output channel. 
Each channel can be configured for either voltage or current output. Use Table 9-7 to configure 
the jumpers.

V/F Board Switch Settings 

There are 2 different types of current outputs, Non-Isolated (std equipment) and Isolated. Each 
requires a different switch setting shown below. If you are operating the instrument in voltage 
output mode, the switches should be set to the desired voltage range.
