6.10. FREQUENCY (DUTY CYCLE) MEASUREMENTS (ELECTRONIC) 1. Set the function switch to the Hz/% position. 2. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive Hz jack. 3. Touch the test probe tips to the circuit under test. -
Page 14: Auto Ranging/Manual Range Selection
6.13. AUTO RANGING/MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into Auto Ranging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following: 1. -
Page 15: Hold
6.17. HOLD The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the HOLD function. 6.18. PEAK HOLD The Peak Hold function captures the peak AC or DC voltage or current. The meter can capture negative or positive peaks as fast as 1 millisecond in duration. -
Page 16: Auto Power Off
6.20. AUTO POWER OFF The auto off feature will turn the meter off after 15 minutes. To disable the auto power off feature, hold down the MODE button and turn the meter on. "APO d" will appear in the display. Turn the meter off and then on again to re-enable the auto power off feature. -
Page 17: Battery Installation
7.1. BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. Turn power off and disconnect the test leads from the meter. 2. Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver. -
