Solution
• Check dip switch setting & proper chart
• May also be hysteresis, see page 4, "Pens"
• Need for pen adjustment, see page 4, "Pen Adjust"
• Keypad may be locked, check dip switch #8
• Slower, firmer key presses (may take multiple presses)
• Check AC adapter connection (widen prongs of adapter to
fit together)
• Display may be off, check dip switch #7
• Probe should be dried out under normal ambient conditions
–time required varies on temperature, RH and air flow
• Alarm sounds audibly for 60 seconds if out of range
conditions occur, then indicator will flash until alarm key is
depressed and alarm is reset (depress MIN/MAX keys for
information)
• Factory repair is necessary, send to Dickson for repair
• Instrument exposed to harsh environments or stressful
conditions, see "Calibration" procedure in manual
• Return to factory for re-calibration
• Check dip switch #7, switch should be off
• Check both dip switch #7 & #8. Both should be off to
allow operation
• Pen may need to be replaced, moistened, or sanded
• Remove pen cap
• Temperature being monitored is too high, see pg. 2
• Temperature being monitored is extremely cold or probe
