Several indicators are provided to identify the current mode and/or status.
PRESSURE UNITS – Pressure units are indicated by an identifier bar. The RANGE key
will toggle the pressure units among PSI, mmHG, inH
2
O and cmH
2
O. The following is a
breakdown of the available pressure units and the measurement range for each:
Identifier Bar Pressure Units Range
PSIG -13.50 to 100.00
mmHg @ 20 °C -701 to 5190
inH
2
O 20 °C -374 to 2773
(flashing)
cmH
2
O 20 °C -951 to 7043
NOTE: If the measured pressure is outside of the range of the instrument, the display will
display -HI- or -Lo-.
TEMPERATURE UNITS (MODEL DPM-2100 ONLY) – The temperature can be
displayed in either degrees Celsius or Fahrenheit. When temperature is displayed, the
RANGE key will toggle the temperature units between Fahrenheit and Celsius.
Temperature Units Temperature Range
C (Celsius) 0.0 to 100.0 °C
F (Fahrenheit) 32.0 to 212.0 °F
NOTE: If the measured temperature is outside of the range of the instrument, the display
will display -HI- or -Lo-. If a probe is not connected, the display will show “no probe”.
LOW BATTERY – When the battery life reaches 10 percent, the display will show the
message “lo bat” for two seconds once every minute until the battery is replaced.
LINE POWER – The display will show “Line” instead of batter life remaining when the
meter is powered from the optional Battery.
DEF CAL – This status screen displays on Power Up if the unit is out of Calibration. The
unit will load default values, however the unit should be returned to BC Group for
Calibration.
