The Ezecal MK4 is a highly versatile, high accuracy instrument, suitable for both simulation and measurement of thermocouple e.m.f.'s and also provides a millivolt source of +/- 99.99mV. When in thermocouple mode it can simulate any of the B.S. Standard Thermocouples over their complete working range and eliminates the need for "look-up" tables, cold junction calculations and temperature unit conversations. Simply set in the appropriate temperature via the keypad. Temperatures can be in degrees Celsius or Fahrenheit, and C.J.C. can be manual or automatic. The Ezecal MK4 is the ideal instrument for calibration checks on temperature recorders, indicators and controllers, and. - used as a millivolt source, for setting up transducers. All necessary operations are set up via a 16 position membrane type keypad; the easy-to-read display shows temperature thermocouple type, cold junction mode and temperature units. When a number of instruments of the same type are to be checked at various points over their range, "LEARN" mode can be used to "teach" the Ezecal MK4 the required values. "Recall" selection and operation of a single key then selects the appropriate value. Alternatively, by use of the time-base facility, the pre-selected values can be automatically stepped through at pre-set intervals. During this sequence the display shows which step in the programme is operational. Unlike many more expensive simulators, the Ezecal MK4 does not "forget" stored values when switched off - this saves a lot of time checking instruments spread over a factory site. A logging facility allows up to 50 measured values to be stored for later examination. The Ezecal MK4 can then be made to compute maximum, minimum and average values. Powered from 4 x AA Nickel/Cadmium rechargeable batteries the Ezecal MK4 provides up to 20 hours of continuous use. Batteries can be recharged by a mains charger or in a car via a lead, available from FGH, that plugs into the cigar lighter. A smart durable carrying case with shoulder strap can also be provided. At a size of only 200 x 100 x 45mm and 470g in weight, the Ezecal MK4 is almost a pocket instrument, and is an essential part of any instrument engineer/technician's equipment. The Ezecal MK4 includes 240V (optionally 110V) mains charger unit & carrying case with cable storage compartment. It costs considerably less than comparable specification calibrators. |
