• Calibration Mode = Factory use only
• A2D Ref. Resistor = Factory use only
• Pressure Cal Current = Calibration value for the electronics and pressure transducer
combination. Consult factory for value.
• Pressure 9Cs = Nine pressure coefficients unique to the pressure transducer. Use the
⇒ to access all nine coefficients.
o Press. Max psi = Based on installed sensor
• Press. Min psi = 0 psiaRTD1. Press the ⇒ to access:
o Ro = RTD resistance at 0°C (1000 ohms)
o A = RTD coefficient A (.0039083)
o B = RTD coefficient B (-5.775e-07)
o RTD1 Max Deg. F = 500
o RTD1 Min Deg. F = -330
• RTD2 = Second RTD configuration, for special applications only.
• Correction Pairs
o ft3/sec (1 through 10)
o %Dev. (1 through 10)
• Roughness = Factory use only
• Force Recal? = Factory use only
• Min. Delta H = Energy EMS meters only. Sets the deadband for totalization to begin.
Must be greater than this number (1 default) to initiate the totalizer.
• Init Displ. (sec) = Enter a value in seconds to initialize the display every xxx seconds.
Enter a value of 0 to disable initializing the display.
5.2 ANALOG OUTPUT CALIBRATION
To check the 4-20 mA circuit, connect a DVM in series with the output loop. Select zero or full
scale (from the second level of the hidden diagnostics) and then press the ENTER key twice. This
action will cause the meter to output its 4 mA or 20 mA condition. If the DVM indicates a current
greater than ± 0.006 mA from 4 or 20, adjust the setting up or down until the output is calibrated.
Note: These settings are not for adjusting the output zero and span to match a flow range. That
function is located in the Output Menu.
