Overview  1 —— Overview INTRODUCTION Thank you for choosing the nVision Reference Recorder from Crystal Engineering Corporation. The philosophy behind nVision: nVision lets you visualize measurements graphically, with or without a pc, in real time as it is being recorded. It is much easier to identify trends or anomalies visually, than in tables of data or spreadsheets. nVision is tremendously flexible and can be configured to measure and record a variety of combinations of measurements.

—— Functions  3 Functions ON/OFF Power button Press and hold the ( power) button for 1 second to turn the nVision on or off. The nVision will automatically power down if not used for the time period defined in CrystalControl. Automatic Shutoff - Low Power Mode Adjust your Automatic Shutoff time (shut off time in absence of key press) to optimize battery life. This feature is adjustable from 30 seconds to “always on.” During a recording, the nVision will enter Low Power Mode instead of shutting off.

Functions  4 Zero To zero the nVision: • Press the (zero) button for at least 1 second while vented to atmosphere until the dashed lines (- - - - -) appear. To clear the zero value: • Hold the (zero) button for 5 seconds until the display changes from (- - - - -) to the zeroed value, then to (- - -). You can adjust the Zero Limit at which the (zero) button will display “- -HI- -” in CrystalControl.

—— Functions  6 GRAPHING Navigating the Graphical Display In the graphical modes the nVision navipad enables you to control how you view your data. The ( ) & () keys allow you to navigate to specific points along your run, while displaying reading and time information. The () & () keys allow you to zoom in and out of your recorded run to suit your needs.

—— —— Functions  7 AVERAGING MODE Averaging mode reports the average reading during the recorded run. If this screen is enabled, data displayed here represents the average of all past data points, over the duration of a recording. The start date and time, duration of the recorded run, and the live reading are displayed. nVision calculates averages as follows: r1 + r2 + r3 ...
PAGE 10
Functions  8 Tare Using the Tare function improves your differential measurement uncertainty significantly if used properly. The Tare function equalizes (normalizes) the nVision’s two modules at a non-ambient datum. The Tare reading displays the same units as the main ΔP or ΔT reading. If you apply the same static line pressure, temperature, or resistance signal to both sensors simultaneously, you should have a differential reading of zero.

—— Modules  16 Modules MODULE INSTALLATION INSTRUCTIONS The nVision’s upper and lower bays allow for removal of modules in the field. All module changes should be completed in a dry, clean environment, indoors. Proper electrostatic discharge (ESD) grounding techniques should be taken into account prior to the module change over. If you’re removing a module without installing a replacement, a blank plate (P/N: BNKPLT) must be installed to ensure your IP67 rating and to protect the product.
PAGE 19
Modules  17 5 Install a new module in the same orientation as the one removed in step 4. The tri-lobe design of the module will not allow improper installation; do not force installation of the module as permanent damage may occur. To ensure an IP67 rated seal, lightly lubricate the module’s o-ring (P/N: 4110) with Dow 111 silicon lubricant or equivalent. (4x) Lightly lubricate the o-ring, then install the module in the proper orientation.

Modules  21 Differential Pressure Measurement Uncertainties without Tare The total nVision Reference Calibrator measurement uncertainty in the ΔP mode configuration will need to consider the uncertainties of both pressure modules. We recommend the module uncertainties to be combined with the preferred square root of the sum of the squares (or “root sum squares”) method. The following table lists the possible combinations of combining Pressure Modules (PM) with different accuracy statements.

—— Modules  23 BAROMETRIC REFERENCE (BARO) MODULE INSTRUCTIONS Installation of the BARO module in the power bay allows you to convert your gauge pressure measurement to the absolute scale if so desired. You may also view the barometric reference reading directly on a dedicated numerical screen. When the BARO module is installed, it may also be disabled in CrystalControl to conserve battery power, however your nVision will not be able to display absolute readings unless it is active.
PAGE 26
—— Modules  24 BAROMETRIC REFERENCE (BARO) MODULE SPECIFICATIONS Absolute pressure mode is achieved by using the BARO Reference Module to establish a datum. The PM and BARO sensor uncertainties were combined to establish a new accuracy statement for readings taken in the absolute mode. It must be noted that the accuracy statement is valid for readings of 1 barA or greater. Accuracy ± 0.00725 PSI, ± 0.

Each mode may be selected via the Setup menu, and can only be operated one at a time. To ensure proper connection to the MA20 Module use the following strategy: 1 Ensure that power is off on the circuit that you are about to measure.
PAGE 29
Modules  27 XX Current Measurement The nVision may be used to measure current up to 50mA. Select the desired current mode through the Setup menu to properly configure the nVision prior to connection and use. XX Current Measurement with HART Resistor The nVision may be used to measure current in a circuit that includes a HART transmitter or device. For devices that use the HART protocol, a load resistor must be placed in the loop. The HART input on the MA20 provides a 250 Ohm load resistor.

Modules  31 Connecting your RTD to the RTD100 Module Your nVision RTD100 module has been shipped with an IP67 rated, M8 connector (P/N: 3953). The terminal block based connector allows you to attach your RTD sensor for 2-, 3-, or 4-wire connections. Care must be taken to install the RTD connector shell properly to ensure the robust IP67 sealing. 1 RTD sensor element connection requirements: • 100Ω Platinum RTD with: • • • TCR of 385, 3926, or 3911 Cable diameter of 3.5 to 5.0mm [0.14 to 0.

Support  48 Error 1 displayed XX Reason The nVision checks the integrity of internal calibration coefficients every time it’s turned on. If any coefficients have been corrupted in any way, “Error 1” is displayed. XX Solution Contact factory for instructions on how to restore the memory to the original factory settings. Error 2 displayed XX Reason The nVision has tried to display a number too large for the display (i.e., more than 6 digits). May be due to an electrical malfunction or numerical error.
PAGE 51
—— Support  49 CALIBRATION If adjustment is required, we recommend returning the nVision or separate modules to the factory. Factory service offers benefits you won’t find anywhere else. Factory calibration tests your nVision at a variety of temperatures utilizing NIST traceable standards, resulting in calibration certificates that provide performance data over temperature. Our calibration facilities are A2LA accredited to ISO 17025:2005 & ANSI/NCSL Z540-1-1994.
PAGE 52
Support  50 Calibration for Current, Voltage & Switch Test Module (MA20) The MA20 can be calibrated through the use of the span factor (userspan) and the Offset for the current and voltage modes. Record displayed current or voltage for two or more points. Determine if the nVision would benefit from an overal increase or decrease of the indicated reading and modify using the userspan and offset feature of CrystalControl.
