707Ex mA Calibrator Calibrator Capabilities Introduction WWarning Read Safety Information before you use the Calibrator. The Fluke 707Ex mA Calibrator (hereafter, "the Calibrator") is a compact and easy to operate sourcing and measuring tool. The Calibrator tests current loops of 0-20 mA or 4-20 mA and measures dc voltage to 28 V. It comes with a set of alligator-clip test leads, a 9 V alkaline battery installed, and this Users manual on a CD.
707Ex Users Manual Battery Saver The Calibrator automatically turns off after 30 minutes of inactivity. To reduce this time or disable this feature: 1. With the Calibrator OFF, press D. P.S. xx is displayed, where xx is the turn-off time in minutes. OFF means the power saver is disabled. 2. Turn k to decrease or lto increase the turn-off time. To disable, turn k until the display shows OFF. 3. The Calibrator resumes normal operation after 2 seconds.
mA Calibrator Safety Information • • • • • • • Never use the Calibrator with the red holster removed. Never use the Calibrator with the case open. Opening the case violates Ex Approval Make sure the battery door is closed before you use the Calibrator. Replace the battery as soon as the M (low battery) symbol appears to avoid false readings that can lead to electric shock. Remove test leads from the Calibrator before opening the battery door.
707Ex Users Manual Safety Regulations Ex-Certification Data The use of this 707Ex mA Calibrator meets the requirements of the regulations providing that the user observes and applies the requirements as laid down in the regulations and that improper and incorrect use of the unit is avoided. • ATEX Certificate of Conformity: ZELM 02 ATEX 0120 X • Certification: ( II 2 G EEx ia IIC T4 • Permitted for zone1, Equipment Group II, gas group C hazardous gases, vapor or mist, Temperature class T4.
mA Calibrator Front Panel Controls Front Panel Controls Control D A+D (Power-on Option) Function ON or OFF button. Press A and D simultaneously to toggle between the mA output spans. • 4 mA to 20 mA = 0 % - 100 % (default) • 0 mA to 20 mA = 0 % - 100 % (optional) Control Function B Press B to step the current up 25 % of full scale (20 mA). At full scale, press B to step the current down 25 % of full scale. B+ C The selection is saved until it is changed.
707Ex Users Manual Using the mA Sourcing (Output) Modes The Calibrator outputs current for calibrating and testing 0 to 20 mA and 4 to 20 mA current loops and instruments. In SOURCE mode, the Calibrator supplies the current. In SIMULATE mode, the Calibrator simulates a 2-wire transmitter in an externally powered current loop.
mA Calibrator Simulating a Transmitter Simulating a Transmitter Auto Ramping the mA Output When simulating the operation of a transmitter, the Calibrator regulates the loop current to a known value selected by you. A 12 V to 28 V loop supply must be available. Insert the test leads as shown below. Auto ramping allows you to continuously apply a varying current from the Calibrator to a passive (sourcing) or active (simulate) loop. Your hands remain free to test the transmitter’s response.
707Ex Users Manual Using the SpanCheck Function Measuring dc mA When in source mode the SpanCheck™ function checks the zero and span points of a transmitter in either SOURCE or SIMULATE mode. W Caution To prevent damage to the unit under test, ensure that the Calibrator is in the correct mode before connecting the test leads. To measure dc mA: To select SpanCheck, press C. To exit, press any pushbutton or turn the knob. 1. 2. Press A to step to MEASURE mode. MEASURE mA is displayed.
mA Calibrator Measuring dc mA with Loop Power Measuring dc mA with Loop Power W Caution To prevent damage to the unit under test, ensure that the Calibrator is in the correct mode before connecting the test leads. Loop Power provides power to a transmitter (up to 700 Ω load) and simultaneously measures the loop current. To measure dc mA with Loop Power: 1. Press A to step to Loop Power mode. 2. MEASURE mA and Loop Power are displayed. 3.
707Ex Users Manual HART Compatibility When in source mode the Calibrator has > 250 Ohms of series resistance and is compatible with HART devices without needing an additional series resistor. Measuring dc Volts W Caution To prevent damage to the unit under test, ensure that the Calibrator is in the correct mode before connecting the test leads. To measure dc Volts: 1. Press A to step to MEASURE mode. 2. MEASURE V is displayed. 3. Touch test lead probes across the load or power source.
mA Calibrator Maintenance Maintenance W Warning To avoid electric shock, personal injury, or damage to the Calibrator: In Case of Difficulty • Make sure you are using the Calibrator as described in this Users Manual and the Fluke 707Ex CCD (Concept Control Drawing). Do not service this product. To maintain the integrity of the Calibrator in explosive atmospheres return the Calibrator to Fluke for all repairs. • Check the battery and test leads.
707Ex Users Manual Replacing the Battery W Warning To avoid false readings, which could lead to electric shock or injury, replace the battery as soon as M (low battery indicator) appears on the display. Do not remove or install the battery within the Ex-hazardous area. Use only a single 9 V alkaline battery, properly installed, to power the Calibrator. See the table on next page for a list of approved batteries. To replace the battery: 1. Remove the test probes from the input signal. 2. 3.
