TROUBLE SHOOTING
If the meter locks on a particular display, unplug and plug in again to unlock the display. A total reset defaults all scaling values to zero. To perform this reset,
Factory Channel settings:

| MODEL NO. | MODEL NO. | MODEL NO. |
CHANNEL NOS. | DPS3000 | DPS3000 | DPS3000 |
CHANNEL 1 | Millivolt | J T/C | Thermistor |
CHANNEL 2 | Voltage | Voltage | Voltage |
CHANNEL 3 | Current | Current | Current |
CHANNEL | Millivolt | J T/C | Thermistor |
(Channels 5,6 & 7 for DPS3100 & DPS3200 only)
