1630-2/1630-2 FC Users Manual Setup Push to change these settings: • Log interval • Alarm threshold • Time • Clamp settings 3. Push / to increment/decrement the interval by 1 second. 4. After you select the value, push until the digits stop blinking. 5. Push to go back to the measurement mode. Log Interval The time interval for data logging is the time between measurements. To set the log interval: 1. Push until LOG INTERVAL shows in the display. See Figure 1.
Earth Ground Clamp Setup Alarm Threshold In alarm mode, the display shows ALARM and the beeper sounds when the measurement is outside the set threshold. The Clamp compares the reading with the high and low values. If the reading is larger than the high value, the Clamp beeps and shows -- on the display. If the reading is less than the low value, the Clamp beeps and -- shows on the display. To set the alarm threshold: 1. Push until ALARM shows in the display. See Figure 2. 2.
1630-2/1630-2 FC Users Manual Time/Clock Backlight Auto-Off The Clamp has a time setting that is used as a timestamp for logged data. A backlight on the display improves visibility in dim light. To conserve battery power, turn off the backlight. To check or adjust the time setting: To change the backlight option: 1. Push until TIME shows in the display. See Figure 3. 1. Push until : shows on the display. See Figure 4. 2. Push until the digit you want to change starts to blink. 2.
Earth Ground Clamp Setup Power Auto-Off Firmware Version To save battery power, you can set the clamp to automatically turn off the power after 20 minutes of no use. To view the firmware version for the Clamp: 1. Push until : shows on the display. To change the Auto-Off option: 2. Push until : and the version number shows on the display. See Figure 6. 1. Push until : shows on the display. 2. Push until : shows on the display. See Figure 5. 3.
30-2/1630-2 FC Users Manual How to Use the Clamp This section is about how to set up the Clamp for Earth resistance tests, AC leakage current measurements, and the Fluke Connect Wireless System. The Clamp includes a trigger lock on the trigger. Push the jaw trigger lock and trigger together to open the jaw. Ground Resistance Measurements The Clamp generates a voltage to the system under test and the induced current in the system is measured by the Clamp.
Earth Ground Clamp How to Use the Clamp 2. Verify that the display reading is within specification, see Table 4. • If the reading is not within specification, clean the heads of the Jaw and repeat step 1 and step 2. • If the reading is within specification, remove the Jaw from the Standard Loop Resistance. The Clamp is ready for a ground resistance measurement. For ground resistance measurements: 1. Open the jaw and make sure the jaw is free of dust, dirt, or any foreign substances. 2.
1630-2/1630-2 FC Users Manual Note • If >3 A is found in the ground rod, NOISE shows on the Ground resistance measurement principle: Ground resistance measurements principle: display and the Clamp beeps. When noise is present, the Clamp reading is not valid. • If the jaw assembly is opened during measurement, shows on the display.

Earth Ground Clamp How to Use the Clamp Single-Phase Two-Wire Circuit Single-Phase Two-Wire Circuit For an AC leakage current measurement test: 2. Turn on the Clamp. 3. Push to select the A function. 4. Attach the Clamp to the electrode, conductor, or ground rod for measurement. Figure 9 shows several connection types for an AC leakage current measurement. 5. Read the value of the leakage current on the display.
1630-2/1630-2 FC Users Manual Logging Measurements Hold The Clamp records data over time and saves >2000 measurements in memory at the set logging interval. Push to freeze the measurement value on the display. To start logging measurements, push . The display shows to indicate that measurement logging is in progress See Figure 10. AC Figure 10. Logging Measurements Measurements are recorded at the sampling interval you specified. See Log Interval on page 8 for more information.
Earth Ground Clamp How to Use the Clamp Fluke Connect Wireless System Fluke Connect App The 1630-2 FC supports the Fluke Connect Wireless System (may not be available in all regions). Fluke Connect uses low-power 802.15.4 wireless radio technology to connect the Clamp with an app on your smartphone or tablet. The wireless radio does not cause interference with meter measurements. The Fluke Connect app works with Apple and Android mobile products.

Earth Ground Clamp Memory Memory 2. Press / to go to the next or previous ID# (memory location). The ID# rolls over when you reach the first or last record. 3. Push to toggle the display to show the time or date for the logged measurement. See Figure 13. You can log >2000 measurements in the Clamp memory. View Memory To view logged measurements in memory: 1. Push and hold >2 s to go the view memory mode. The most recent logged measurement shows on the display with an ID#. See Figure 12.
1630-2/1630-2 FC Users Manual Maintenance Warning To prevent a possible electrical shock, fire, or personal injury: • Do not operate the Product with covers removed or the case open. Hazardous voltage exposure is possible. • Repair the Product before use if the battery leaks. • Use only specified replacement parts. • Have an approved technician repair the Product. • Remove the input signals before you clean the Product. • Do not use the HOLD function to measure unknown potentials.
