2. Change the input voltage to 1 volt. Adjust R12 until the upper
current level is achieved.
3. Repeat 1 and 2 until repeatability is achieved.

1. PCB strappings (jumper wires) for set point alarm actuation are
as follows:
Dual: Above-Above: A to F & E, B to G, C to D
Dual: Below-Below: A to G & D, B to F, C to E
Dual: Above-Below: A to F & D, B to G, C to E
Dual: Below-Above: A to G & E, B to F, C to D
Single: Below: A to G, B to F
Single: Above: A to F, B to G
2. Single Alarm PCB:
full clockwise position of P2 (setting of 1000). If the instrument
output of the alarm is set for 1 volt full scale the alarm is set for 1
volt full scale. The alarm relay should activate or deactivate
within +2% of the P2 dial setting.
3. Dual Alarm PCB: Same as above, except both relays should
activate or deactivate within +2% of P2 and P3 dial settings.
