52 | 5000 Single-Point Moisture Analyzer
Oven Temperature Adjustment
Perform this procedure as quickly as practicable to keep cooling from affecting the read-
ings.
1. Carefully remove the field unit lid and set it aside.
2. Remove the plug from electronic control board socket J1.
3. Quickly connect a DVM, set to read ohms, between pins P1-1 and
-4 (on body of J1) and check for the resistance specified on the oven
thermistor label (also on J1), ± 200 ohms.
4. If necessary, adjust R17 one turn for each 1000-ohm (»1°C) difference
between the specified and actual resistances. (Turn clockwise to de-
crease resistance.)
5. Remove the DVM and connect the oven plug to J1.
6. Re-install the lid.
7. Apply power to the system and allow it to warm up.
8. If necessary, repeat the procedure until no further adjustment is re-
quired to maintain 60 °C.
Moisture Generator Temperature Adjustment
Perform this procedure as quickly as practicable to keep cooling from affecting the read-
ings.
1. Carefully remove the field unit lid and set it aside.
2. Remove the plug from electronic control board socket J2.
3. Quickly connect a DVM, set to read ohms, between pins P2-2 and -3
and check for the resistance specified on the moisture generator label,
± 200 ohms.
4. If necessary, adjust R26 one turn for each 1000-ohm (»1°C) difference
between the specified and actual resistances. (Turn clockwise to de-
crease resistance.)
5. Remove the DVM and connect the moisture generator plug to J2.
6. Re-install the lid.
7. Apply power to the system and allow it to warm up.
8. If necessary, repeat the procedure until no further adjustment is re-
quired to maintain 60 °C.
