DewPro MMY245
Cell Function
V3 H9 Calibrates the output 1 hardware at 5 V: connecting a voltmeter to the output the
displayed number can be increased or decreased using the + and - button to adjust the
voltmeter reading to 5 V (Value is around 2500). This is factory calibrated.
V5 H2
Scaling the output the low pressure value is assigned to 0 V. The value indicated will
assign the "0" volt output to track the pressure transmitter. It will also function to
respond to the pressure constant if no optional pressure sensor is installed.
V5 H3
The high pressure value is assigned to 5 V. The value indicated will assign the "5"
volt output to track the pressure transmitter. It will also function to respond to the
pressure constant if no optional pressure sensor is installed.
V5 H4
Using the scaled input with any sensor (e.g. oxygen sensor) the low value to be
displayed is entered here.
V5 H5 Using the scaled input with any sensor (e.g. oxygen sensor) the high value to be
displayed is entered here.
V5 H6
The minimum voltage (0 V = minimum) external sensor electronics would supply is
entered here in Volts.
V5 H7 The maximum voltage (5 V = maximum) external sensor electronics would supply
is entered here in Volts.
V7 H8
Calibrates the output 2 hardware at 0 V: connecting a voltmeter to the output, the
displayed number can be increased or decreased using the + and - button to adjust the
voltmeter reading to 0 V (Value is around 500). This is factory calibrated.
V7 H9
Calibrates the output 2 hardware at 5 V: connecting a voltmeter to the output the
displayed number can be increased or decreased using the + and - button to adjust the
voltmeter reading to 5 V (Value is around 2500). This is factory calibrated.

2.5.6 Interconnection

The MMY 245 can be powered from an external DC power supply and can provide voltage outputs for
recording purposes. The paragraphs below describe these functions.
WARNING! The MMY 245 is not designed to be connected to either an external
power supply or external signals for inputs or outputs in hazardous or electrically
classified areas.

2.5.6.1 External Power Option

The DewPro MMY245 can be powered with 6-12 VDC using the power and output cable P/N 63002013.
This cable will allow connection of the DC power using the Red (+) and Black (-) wires per the drawing
MSY35C in the appendix of this manual.
WARNING! The MMY 245 has a maximum voltage specification of 12 VDC.
Connecting the unit to a higher voltage could cause damage to the unit and will void
the warranty.

2.5.6.2 External Scalable Input Option.

The DewPro MMY245 can display an external analog input using the power and output cable P/N
63002013.

2.5.6.3 Voltage Inputs

The cable P/N 63002013, will allow connection of the DC 0/1-5 VDC signal using the Orange (+) and
Black (-) wires per the drawing MSY35C in the appendix of this manual. This input can be scaled and
