Page 6 1.0 Product description The 4840 sensor simulator is a hand held, battery operated signal generator designed specifically to simulate the electrical output of common types of sensors. The instrument contains a highly accurate oscillator with an adjustable output level and is ideal for setting up, testing and the diagnosis of faults within data acquisition systems, FFT analyzers, environmental test systems or simply as a flexible signal generator.

Page 8 3.0 Bridge Output configuration The Bridge output consists of 2 low impedance AC signals produced on S+ and S-. When connected to the “Signal +” and “Signal –“ inputs of a differential amplifier, the output signal can simulate equivalent levels of a many bridge based sensors. The “Excitation +” and “Excitation –“ connections of the bridge sensor are ignored.
Page 9 4.0 Basic operation 4.1. Menu structure The simulator menus are accessed via the three menu keys as shown in Figure 2 below. Figure 2: Menu structure 4.2. Home screen Depending on the seleced “Unit Display” (see section 3.5.3) the home screen is either in two parts, upper and lower, when “Unit Display”...
Page 10 Figure 3: Home screen, upper Figure 4: Home screen, lower 4.3. Editing screen The editing screen is accessed by pressing either the left or right arrow keys when in the home screen. The editing screen is in two parts, i.e. primary and secondary parameters, when the unit display is set to g. Otherwise, only the single screen is availalble.
Page 11 Displacement (mm) – only available when Unit Display = g • Velocity (m/s) – only available when Unit Display = g • In terms of simulating an sensor, the primary parameters are: sensitivity, signal level (g, PSI, Bar,dB,dBA, or kPa), frequency and waveform type. These are displayed in the upper home screen. The secondary parameters, which are only available when the unit display is in g, are obtained by calculation, taking into account the frequency and acceleration level.
Page 12 Scroll up or down with the arrow keys to move the cursor (inverted text) to the required field, and press the ENTER key. Configuration Within the configuration menu, further menus are selectable; refer to Figure 2 for details. 4.5.1.1. Clock The simulator has a real time clock installed primarily to record the date when a calibration is performed.
Page 13 Download data Selecting this menu option prepares the simulator for communication with a PC allowing the download of user profiles into the simulator and the synchronization of the real time clock. About Select to see information on the date of manufacture (D.o.M), the serial number of the simulator, firmware revision and the date of the last calibration.
Page 14 IEPE sensors have an output where the AC vibration signal is superimposed upon a DC bias level. The DC bias level is typically in the range of 10 to 12V and is result of the constant current, normally in the range of 2mA to 20mA, from the IEPE power supply.

Page 16 Figure 11: Typical connection configurations 5.0 Detailed operation 5.1. Parameter editing The editing function is the same process for all parameters with the exception of Type. From the home screen, press either the left or right arrow keys to enter the editing screens. Using the up and down arrow keys, move the cursor (inverted text) to the parameter to be edited, and select by pressing the ENTER key.
Page 17 Back calculation The secondary parameter values can be edited in the same way as the primary parameters, i.e. “Freq”, “Sens” and “g level”. As the simulator is simulating an sensor having an output as a function of acceleration g, then any change in the value of a secondary parameter must affect the value of the primary parameter g.
Page 18 A short message follows indicating the profiles are being saved to memory. The display will now look like this: Figure 17: Profile after save Press ENTER to load and view the profile. The upper home screen now shows the user profile name. The profile parameters can now be edited as previously described in paragraph 4.1.
Page 19 5.6. Setting the clock From the home screen press the TOOLS menu key. Using the down arrow key, step through the menu until “CONFIGURATION” is highlighted. Press the ENTER key. In the configuration menu step through the menu until the word “Clock” is highlighted. Press the ENTER key. The clock screen is now visible - time and date are displayed.
Page 20 The backlight can also be toggled on or off by pressing and holding down the home key for approximately 3 seconds. Note that when in the FFT mode, the backlight will remain ON, if selected, i.e. the 30 second timer is disabled in this mode. 5.8.
Page 21 5.11. Battery charging Power for the simulator comes from an internal Li-on cell pack, and a supplied external universal power adapter. The power adapter functions as a charger for the internal battery, but also will power the simulator in addition. Battery charge and discharge are managed by internal circuitry to provide a safe and effective environment for the battery to operate.
Page 22 Preliminary instructions Allow 30 minutes for the test equipment to temperature stabilize before performing this • procedure. Connect the AC voltmeter/DMM and oscilloscope to the mV/IEPE BNC output socket. • Locate the calibration password. • Ensure that the simulator battery is fully charged. •...
Page 23 Measurement 2: Change the g level setting to 1000.0. The DMM reading should be within the range 7.000 to 7.141 V rms. If the values measured are not within the ranges stated then repeat the “Adjustment 1” step, setting the output to a level whereby the values measured and recorded in Measurements 1 and 2 come within range.
Page 24 7.2. Installing the utility software The PC should meet the following minimum specifications: 1 GB available hard disk space • DVD drive • SVGA (880 x 600 ) or higher resolution monitor • 1 GHz Pentium® IV processor (or equivalent) for Windows XP •...
Page 25 Figure 25: Utility software main screen Note that a set of 10 profiles are pre-loaded into the table. These have been loaded as part of the installer as working examples and are stored in the path shown in the profile set dialogue box. Take time to familiarize yourself with how they are constructed.
Page 26 Enter the number of profiles required to make up the profile set. Click the “Create Profiles” button to generate the base template. A new window will open. Give the profile set an identification name and save to the profile sets folder. A message then appears confirming that the profiles are ready to use.
Page 27 Figure 28: Output socket select warning screen 7.3.2.4. Editing a parameter All parameter values can be edited either by highlighting with the mouse and overtyping, using the increase or decrease arrow keys at the side of the parameter field or the up and down arrow keys on the keyboard.
Page 28 All profiles within a set can be selected or deselected for download from the “Set Download Markers” pull-down menu. When selected a green tick appears above the profile notes box, if not then a red cross is shown. 7.3.2.7. Reset button Provides a quick way to reset the profile parameters to default.
Page 29 Figure 30: Device Manger With the utility software open, click on the “PC Comms” tab. Select the allocated port number from the pull down menu. 7.3.7.1. Download profiles Open a profile set and ensure that some or all of the profiles are selected for use. Connect the simulator to the host PC using the supplied USB cable.
