KFN-TM:

Access to conductor plate:

• Remove seal

• Open display unit

• The application of the display unit as a weighing system able to be verified

requires that the contacts of the circuit board are short-circuited with the help

of a jumper [K1]. For non verifiable weighing systems remove the jumper.

• To adjust, short-circuit the contacts of the circuit board, using a jumper [K2].

Why KERN Monitor is not turning on?
- T
  Tracy WilsonAug 25, 2025
  There are several potential reasons why your KERN Monitor might not be turning on. It could be due to a faulty power switch connector, a depleted battery, or issues within the internal circuitry. Specifically, if the voltage exceeds 6V, the DU4 circuit should be inspected. Additionally, problems in the M/B DU3 and DU1 circuits, as well as the ST circuit, could prevent the monitor from powering on. Ensuring a high level at the M/B DU3 pin 8 is also crucial. You may need to replace the power switch or connector, or recharge/replace the battery.
