1550C/1555 Calibration Manual Display Test Turn the UUT on several times while observing the display during power up. Compare the display with the example in Figure 2. Check all segments for clarity and contrast. 6 5 7 4 8 3 9 2 1 10 11 12 gHH03f.EPS Item Description Interference present. Readings could be out of specified accuracy range.
Insulation Tester Performance Test Procedures Charging Test 1. With the product switched off, connect a mains supply to the ac supply receptacle and check that the UUT display shows Charging. 2. Disconnect the mains supply and check that the UUT turns off. 3. Turn the product on and see that all the battery symbol segments display as shown in Figure 2. Note A fully-charged battery is indicated when the battery symbol shows all segments. Recharge the battery as necessary to obtain all segments.

Insulation Tester Performance Test Procedures Output Voltage Test In Table 4, the UUT output voltage is checked with various loads applied. In this test a voltmeter with a high-voltage probe must be connected to the load resistor to measure the UUT output voltage. Use 15 80K-6 for voltages below 6 kV. Table 4.
1550C/1555 Calibration Manual Voltage Measurement Accuracy To verify voltage measurement accuracy of the Live Circuit Warning function, apply the voltages listed in Table 6 to the + and - terminals of the UUT. Verify that: • The UUT reading is within the display limits of Table 6. • The UUT is beeping at a 1-second interval. • is flashing on the display. Table 6.
Insulation Tester Adjustment Procedure Instrument Setup Turn the product on and wait for Test Voltage to appear on the display. From the computer terminal, activate the Snorre program from the Windows Start menu. On the Setup tab, confirm the selected COM port settings. Warning To prevent possible electrical shock, fire, or personal injury, do not contact the output terminals or test equipment terminals while performing the following procedures.
1550C/1555 Calibration Manual Current Adjustment 1. Select the Cal Current tab. 2. Attach a 2 mA current source to the LO and GUARD terminals of the UUT, connecting the current source LO to UUT GUARD terminal, as shown in the connection diagram. 3. Apply 2 mAdc to the UUT. 4. Press the START button and wait until the adjustment is complete. 5. The current measurement is now adjusted. Disconnect the current source. Charge Adjustment 1. Select the Cal Charge tab. 2.

static awareness A Message From Fluke Corporation Some semiconductors and custom IC's can be damaged by electrostatic discharge during handling. This notice explains how you can minimize the chances of destroying such devices by: 1. Knowing that there is a problem. 2. Learning the guidelines for handling them. 3. Using the procedures, packaging, and bench techniques that are recommended. The following practices should be followed to minimize damage to S.S. (static sensitive) devices. 1.
5. USE STATIC SHIELDING CONTAINERS FOR HANDLING AND TRANSPORT. 8. WHEN REMOVING PLUG-IN ASSEMBLIES HANDLE ONLY BY NON-CONDUCTIVE EDGES AND NEVER TOUCH OPEN EDGE CONNECTOR EXCEPT AT STATIC-FREE WORK STATION. PLACING SHORTING STRIPS ON EDGE CONNECTOR HELPS PROTECT INSTALLED S.S. DEVICES. 6. DO NOT SLIDE S.S. DEVICES OVER ANY SURFACE. 9. HANDLE S.S. DEVICES ONLY AT A STATIC-FREE WORK STATION. 10. ONLY ANTI-STATIC TYPE SOLDERSUCKERS SHOULD BE USED. 11. ONLY GROUNDED-TIP SOLDERING IRONS SHOULD BE USED. 7.
