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 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. • Use must be restricted to the specified application parameters. • Do not open the Calibrator. • Do not remove or install the battery within the Ex-hazardous area. • Do not carry additional batteries within the Ex-hazardous area.
mA Calibrator Front Panel Controls Front Panel Controls Control D Function ON or OFF button. Press A and D simultaneously to toggle between the mA output spans. (Power-on Option) • 4 mA to 20 mA = 0 % - 100 % (default) • 0 mA to 20 mA = 0 % - 100 % (optional) The selection is saved until it is changed. Press to step through modes: • Source mA • Simulate mA • Measure mA • Loop Power (24 V) • Measure V dc Control Function B Press B to step the current up 25 % of full scale (20 mA).
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. 707Ex mA CALIBRATOR Press simultaneously once for slow ramp twice for fast ramp three times for stepped ramp. In SOURCE mode, the Calibrator supplies the current. In SIMULATE mode, the Calibrator simulates a 2-wire transmitter in an externally powered current loop. Press until SOURCE mA is displayed.
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. 707Ex mA CALIBRATOR Press until SIMULATE mA is displayed. Press B + C simultaneously to enter the Auto Ramp mode and step to a ramp type.
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: 1. Press A to step to MEASURE mode. MEASURE mA is displayed. 2. Touch the test probes to the circuit across the load or power source as shown below.
mA Calibrator Measuring dc mA with Loop Power Measuring dc mA with Loop Power W Caution 707Ex mA CALIBRATOR 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. Press until Loop Power is displayed. 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. 707Ex mA CALIBRATOR 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.
mA Calibrator Maintenance Maintenance In Case of Difficulty W Warning To avoid electric shock, personal injury, or damage to the Calibrator: • 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.
