To avoid a violent release of pressure in a pressurized system shut off the valve and slowly bleed off the pressure before you attach the pressure module to the pressure line Caution To avoid possible damage to the calibrator or to the equipment under test Usethe proper terminals function and range for your measurement or sourcing application To avoid mechanically damaging the pressure module never apply more than 10 ft lb of torque between the pressure module fittings or between the fittings and the body of the module To avoid damaging the pressure module from overpressure never apply pressure above the rated maximum printed on the module To avoid damaging the pressure module from corrosion use it only with specified materials Refer to the pressure module documentation for material compatibility Make sure to remove all test connections before powering up the 3001 Failure to do so could lead to damage of the 3001 or the unit under test 2 Calibrator Description 2 1 Front Panel Overview Figure 1 shows the overall layout of the front panel Each of the three major divisions is described in detail in the following sections cu MARTEL MODEL 3001 OUTPUT 100VMAX 0 0002 V Lo Lo Qm LO ca E 20V PK MAX 7 1 5 10V RANGE mA 100 OUTPUT AUTO 0 1 VDC Stby 0 000000 V 4

9. Look for cracks or missing plastic Pay particular attention to the insulation surrounding the connectors Inspect the test leads for damaged insulation or exposed metal Check test lead continuity Replace damaged test leads before you use the calibrator Never operate the calibrator with the cover removed or the case open and never remove the cover or open the case without first disconnecting the power source and all test leads Select the proper function and range for your measurement Never touch the probe to a voltage source when the test leads are plugged into the current terminals When using the probes keep your fingers away from the probe contacts Keep your fingers behind the finger guards on the probes Connect the common test lead before you connect the live test lead When you disconnect test leads disconnect the live test lead first Do not use the calibrator if it operates abnormally Protection may be impaired When in doubt have the calibrator serviced Do not operate the calibrator around explosive gas vapor or dust When using a pressure module make sure the process pressure line is shut off and depressurized before you connect it or disconnect it from the pressure module Disconnect test leads before changing to another measure or source function Have the calibrator serviced only by qualified personnel and use only specified replacement parts Use only the replacement fuse s specified in this manual
