SYSTEM INDICATORS
Four indicators are provided to identify the Current Operating Mode.
PRESSURE SCALE – The pressure scale is indicated by an identifier bar. The RANGE
key will toggle the pressure units among PSI, mmHG, inHg and cmH2O. The following is a
breakdown of the available pressure scales and the measurement range for each scale:
Identifier Bar Pressure Units Pressure Range
PSIG -13.50 to 100.00
mmHg -701 to 5190
inH2O -374 to 2773
bar
no bar
(flashing)
cmH2O -951 to 7043
NOTE: If the measured pressure is outside of the range of the instrument, the display will
display -HI- or -Lo-.
NOTE: InH20, cmH20 and mmHg ranges are calibrated for 20 degrees Celsius.
TEMPERATURE SCALE (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
Degrees C 0.0 to 100.0
Degrees F 32.0 to 212.0
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” once every minute.
LINE POWER – When meter is running from the optional Battery Eliminator (BE2000PU,
BE2000PE), the display will show “Line” instead of the battery life remaining.
5
KEYS – DPM-2001
Four tactile-touch keys are provided for system operation.
ON/SETUP – The function of this key is dependant on the Current Operating Mode as
follows:
POWER OFF – If this key is pressed while the power is turned OFF, the power will
be turned ON
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the Setup Mode will be entered.
SETUP MODE – Pressing this key while in the Setup Mode will sequence the
display through the available parameters.
OFF/RESET – The function of this key is dependant on the Current Operating Mode as
follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the power will be turned OFF
SETUP MODE – Pressing this key while in the Setup Mode will exit the Setup Mode
and automatically save all settings.
6
RANGE/UP – The function of this key is dependant on the Current Operating Mode as
follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will step through the available pressure ranges (PSI,
inH20, cmH20 and mmHg).
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will increment. Pressing and holding this key will cause the rapid
automatic incrementing of the displayed setting.
BATTERY/DOWN – The function of this key is dependant on the Current Operating Mode
as follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will display the percent (0 to 100) of battery life remaining.
NOTE: If the optional wall mount power supply is used, the unit will display
“Line”.
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will decrement. Pressing and holding this key will cause the rapid
automatic decrementing of the displayed setting.
ZERO – This function is a combination of two keys (RANGE/UP and BATTERY/DOWN).
If both keys are depressed and held for 5 seconds, the pressure display will be zeroed.
NOTE: If the BATTERY/DOWN key is depressed first, it will prevent the range from
being changed in the process.
7
KEYS – DPM-2001 PLUS
Six tactile-touch keys are provided for system operation.
ON/SETUP – The function of this key is dependant on the Current Operating Mode as
follows:
POWER OFF – If this key is pressed while the power is turned OFF, the power will
be turned ON
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the Setup Mode will be entered.
SETUP MODE – Pressing this key while in the Setup Mode will sequence the
display through the available parameters.
OFF/RESET – The function of this key is dependant on the Current Operating Mode as
follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the power will be turned OFF
SETUP MODE – Pressing this key while in the Setup Mode will exit the Setup Mode
and automatically save all settings.
MIN/MAX MODE – Pressing this key when a Min or Max Value is being displayed
(MIN or MAX key is held down) will cause that value in that capture register
to be reset to the current reading.
8
MAX/UP – The function of this key is dependant on the Current Operating Mode as follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will display the maximum pressure detected since the
capture register was last reset.
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will increment. Pressing and holding this key will cause the rapid
automatic incrementing of the displayed setting.
MIN/DOWN – The function of this key is dependant on the Current Operating Mode as
follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will display the minimum pressure detected since the
capture register was last reset.
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will decrement. Pressing and holding this key will cause the rapid
automatic decrementing of the displayed setting.
ZERO – This function is a combination of two keys (MAX/UP and MIN/DOWN). If both
keys are depressed and held for 5 seconds, the pressure display will be zeroed.
RANGE – The function of this key is to select the desired display engineering units. When
viewing pressure it will sequence through the four ranges (PSI, inH20, cmH20 and mmHg).
BATTERY - If this key is pressed while the pressure is being displayed, the unit will display
the percent (0 to 100) of battery life remaining.
NOTE: If the optional Battery Eliminator is used, the unit will display “Line”.
