Defective POWER PCB:
If the voltage on CN6 is correct
and the calibrator does not cool
down sufficiently, replace the
well and re-calibrate the unit.
If the voltage on CN3 is less than
18V and the voltage on CN6 differs
from 0.330V ±0.005V, adjust R9
until the voltage is 0.330V ±0.005V.
If it is impossible to adjust the
voltage on CN6, replace the
POWER PCB.
Error: Calibrator does not heat (CTC-320/650 A/B, CTC-1200 A,
MTC-320/650 A).
Likely cause: Solution:
Defective POWER PCB:
Check impedance of the
heating elements:
- approx. 23 ohm for CTC-
320/650 A, MTC-320/650 A
- approx. 44 ohm for CTC-320
B and
- approx. 22 ohm for CTC-650
B
- approx. 4-5 ohm for CTC-
1200 A
Turn on the instrument and set
the SET temperature to:
- 320°C (CTC-320 A/B, MTC-
320 A)
- 650°C (CTC-650 A/B, MTC-
650 A) or
- 1200°C (CTC-1200 A)
Check that relay K1 has been
pulled.
