MiniPrint 4100 Data Printer MiniPrint 4100 provides immediate or later (MiniTest 2100 only) print-out of all single readings and statistics (MiniTest 2100 only). 1. Plug the printer laterally into the MiniTest gauge. 1. Switch the gauge off. 2. Switch on the MiniTest gauge (ON). 2. Press and hold down the CLEAR, FUNC and ON keys. Press these keys one after the other and hold all three down. 3. Switch MiniPrint 4100 into the requested mode (ON / OFF). A long bleep confirms deletion of all data. 6. Using the Gauge without Probe Certain gauge functions can be activated without a probe being connected. These are as follows: 1. Defining the initialising function and standard gauge settings. 2. Print-out of statistics and readings 3. Gauge control via a PC (see section 9). E-42 For fur ther details see MiniPrint 4100 operating instructions. 8. Connecting a PC The MINITEST 1100 and 2100 gauges have a combination interface which can accommodate a MiniPrint 4100 data printer, a Mitutoyo system evaluator and two-way RS232C interface. The connecting cable and the data transfer program can be used to transfer all readings and statistics (MiniTest 2100 only) to a PC for further processing. The data transfer procedure is the same as that for data print-out. ElektroPhysik Note on the Mitutoyo printer DP1-HS: As the Mitutoyo printer DP1-HS works on his own statistics function, the MiniTest statistics cannot be printed out with this printer. For that reason, the statistics provided by the Mitutoyo printer is different from the MiniTest statistics program. 9. Gauge Control via PC The two-way interface can be used to control MiniTest gauge functions via a PC keyboard and a PC program. The option of program control enables the gauge to be used both for semi-automatic and fully automatic operation.For further details consult our special leaflet (interface description). See also section 11. 10. Combination Interface for footoperated Switch, Bleeper or Lamp This optional interface makes available an external trigger mechanism which enters readings in continuous mode into the statistics program by a foot-operated switch as well as a reading confirmed signal for a bleeper or a lamp. Length of reading confirmed signal - 0.2 sec. ElektroPhysik 11. Interface Descriptions MiniTest and MiniPrint for Available on request. 12.

Maintenance and Maintenance Contracts The MiniTest needs an occasional battery change but is otherwise maintenance-free. It is extremely robust, but, as with any measuring apparatus, it should be handled with care. Used batteries must be removed from the gauge without delay. The accumulator batteries in the MiniPrint printer need regular recharging. If the customer takes out a maintenance contract the gauge and all supplementary hardware will be serviced annually. We will gladly supply an estimate for maintenance agreement with further details of the service guarantee. 14. After-Sales Service 15. Trouble Shooting The following list of error messages explains how to identify and eliminate faults. „E“ (E = error). Faults that cause the gauge to switch off: E 1 : Probe type incompatible E 2 : Probe not connected. This message only appears when no probe is connected after a Total Reset. E 3 : Probe defective. This message only appears immediately after the gauge is switched on or if the probe becomes detached from the socket while in use. E 4 : Probe is giving unreliable readings (e.g. as a result of strong fluctuations in the magnetic field or readings taken on soft coatings). Please send a damaged or defective gauge to us directly or forward it via your dealer. E 5 : Probe was held too near to metal when switched on. Please enclose a brief error description. E 6 : Low battery.

Press ON. Measuring Example . The following errors can be remedied by a Total Reset: A long bleep confirms that all readings and calibration values have been deleted If you cannot switch the gauge of via key operation. ElektroPhysik 1. please use the ferrous zero plate supplied with the probe.None or several of the keys work Chose probe according to your application. EC Declaration of Conformity We declare that the gauges MiniTest 1100 and MiniTest 2100 as well as the data printer MiniPrint 4100 are in correspondence with the safety requirements of the EMC directive 89/336/EWG. To check whether gauge and probe work within the specified tolerances. 2. F3. Press FUNC and CLEAR and keep pressed down while pressing ON.g.The gauge does not switch off automatically . 2. 17.
