Page 4: Overview
Overview The Mini-SuperGraph II allows you to monitor ground vibrations and air over- pressure with ease and accuracy. The Mini-SuperGraph II can be used for most vibration and sound monitoring activities including blasting operations, pile driving operations, construction equipment activity, environmental activity, ambient levels, and any other operation where a permanent record is needed. -

Page 6: Operating Instructions
Operating Instructions Point the arrow on the transducer toward the vibration source. IMPORTANT: Connect the transducer and/or microphone cables before turning the instrument on. The transducer and microphone plugs are color coded to allow for easy connections. The quick lock ring on each connector is designed to prevent the connection from coming out. - Page 7 See the Transducer Placement Procedure on pages 10-13 for further instructions on how to make a stable placement. Press the green ON button and WAIT 60 SECONDS for the Nomis Main Menu to appear. Use the ↑ and ↓ keys to select the type of monitoring you want to use (See the Monitor Modes section for details about each available option): ...
- Page 8 This mode provides both the data collection from a period of time and detailed analysis of events over their trigger level. The Super Graphics program allows you to match these files together for a complete analysis. After you select a mode, the screen will display MONITOR and EDIT. ...

Page 12: Transducer Placement Procedure
Transducer Placement Procedure Placement of the transducer block is critical when taking vibration readings. This block must always make firm contact with the surface to ensure an accurate vibration reading. There are very few incidents where the transducer block can be simply placed on the surface for an accurate vibration measurement. - Page 13 Placement Instructions Method Bury This is the most accepted procedure and will produce the most dependable Transducer results. For more information about this procedure, refer to the U.S. Bureau of in Soil Mines Bulletin RI 8506 – Measurement of Blast Induced Ground Vibrations and Seismograph Calibration.
- Page 14 Placement Instructions Method transducer block. This will provide a solid coupling with the soil so that no slippage can occur. Bolt When soil is not available to bury the transducer, you can bolt the transducer Transducer block to a rock or concrete surface. Depending on the anchors available in Block your area, an anchor can be placed in the concrete or rock and a threaded bolt placed through the hole to bolt the transducer block into place.
- Page 15 Placement Instructions Method dig a hole to bury the transducer block. However, once vibration levels exceed .25 ips (6 mm/s), consider burying the transducer block. Sand Bag As a last resort it may be necessary to sandbag the transducer block to on Top of eliminate slippage.
- Page 16 We do not want operators to falsely assume that leveling is the most important aspect of proper transducer installation. The type of geophone elements used in NOMIS Seismographs only require a leveling of 20 degrees or less against the horizon, according to the geophone manufacturer.

Page 17: Monitor Modes
Monitor Modes Three monitoring modes are available with the Mini-SuperGraph II: SELF TRIGGER, BAR GRAPH, and COMBO. If you want to modify the settings for a monitoring mode, select that mode, press the ↓ button to select EDIT and press ENTER. With the EDIT option, a different screen will display each time you press ENTER. -
Page 18: Self Trigger (Waveform) Mode
All activity is stored in internal memory in a numbered event format. Once the recording is complete, the Mini-SuperGraph II returns to a wait mode for the next event that exceeds the trigger levels. - Page 19 Company – User setting for record Seis. Location – User setting for record Notes – User setting for record Distance to source – None, 1-99999 ft (User setting for record) Weight Per Delay – None, 1-99999 lbs (User setting for record) ...
- Page 20 Save Setup – Choose YES or NO to save the setup for later use. If you choose to save settings, enter a name to identify the saved settings. Additional Settings: Alarm 1: Able to set as follows: Off, Seismic, Air, both. If you choose Seismic, Air, or Both, set the trigger level for the sensor(s) selected.

Page 22: Bar Graph
BAR GRAPH This mode is designed for situations where large data collection is needed for long periods of time (normally over 60 seconds and lasting for hours or days). Seismic and/or air data is collected and recorded in a bar graph (histogram) format and stored in the internal memory for future use. - Page 23 When you select BAR GRAPH from the main menu and choose EDIT, you will be able to modify the following settings: Sample Rate – 512, 1024, 2048, 4096, 8192. Faster sample rates are more accurate at higher frequencies, but will create larger files. ...
- Page 24 Bar Interval – 1, 10, 20, 30, 40, 50, 60 seconds. This is the amount of time each bar represents. Summary Interval – 5 min., 10 min., 30 min., 1 hour, 2 hours, 4 hours, 8 hours, 12 hours. Indicates how often a complete summary is saved in the record.

Page 26: Combo
COMBO COMBO mode, a combination of both SELF TRIGGER and BAR GRAPH modes, is designed for situations where both types of data are needed. The files for these will be split into each type and stored. This mode provides both the data collection from a period of time and detailed analysis of events over their trigger level. -

With this feature Mode you can connect external alarms to the unit to indicate when vibration and/or air limits have been exceeded. Choose DISABLED or ENABLED. If you enable the alarm here, you can then go to the Edit menu for the monitoring mode to select two (2) limits of your choice as a caution and not to exceed limit. - Page 29 Feature Description with that record. Bar graph does not store a calibration graph with the event. If a calibration graph is required, enable this option. This feature is intended for use on instruments that are left in place for a number of days at a time.
- Page 30 This option is intended for instances when an operator may forget to put the Mini-SuperGraph II into monitor mode. If you set this feature to “no auto monitor”, the operator will need to press all keys necessary to begin monitoring with the unit.
- Page 31 Feature Description Baud Rate Use this option to set the baud rate of the instrument when some type of modem is in use. The default value for this setting is 38400. Other options are 115200, 57600, 19200 and 9600. This is used for serial communication with the PC as well as modem communication.
- Page 32 Feature Description Erase Use this option if you want to clear all stored events from the memory. Memory Choose YES to erase the memory. CAUTION: With this feature all previously stored data will be permanently deleted. Make sure you have downloaded all useable data prior to executing the erase procedure.

The LCD displays the Summary event number, date, and time of the event. The far right side will display a letter to indicate the mode of operation used when the event was recorded: W for waveform, B for bar graph, C for combo mode, P for calibration pulse.
- Page 34 Feature Description memory is full, but it will write over the oldest events it has stored in memory. Flash Stats Use this option to see how much memory has been used and how much remains at any given time. It also indicates whether or not Flash Wrapping has been activated and how many waveforms or bar graph hours remain at current settings before an overwrite will occur.
