Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired. WARNING To avoid possible electric shock, personal injury or death, follow these guidelines: · Do not use if meter appears damaged. Visually inspect the meter to ensure case is not cracked and back case is securely in place. · Inspect and replace leads if insulation is damaged, metal is exposed, or probes are cracked. Pay particular attention to the insulation surrounding the connectors. · Do not use meter if it operates abnormally as protection maybe impaired. · Do not use during electrical storms or in wet weather. · Do not use around explosive gas, dust, or vapor. · Do not apply more than the rated voltage to the meter. · Do not use without the battery and the back case properly installed. · Remove the test leads from the circuit prior to removing battery cap. · Do not attempt to repair this unit as it has no user-serviceable parts. CAUTION To protect yourself, think "Safety First": · Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution. · Use appropriate personal protective equipment such as safety glasses, face shields, insulating gloves, insulating boots, and/or insulating mats. · Before each use: - Perform a continuity test by touching the test leads together to verify the functionality of the battery and test leads. - Use the 3 Point Safety Method. (1) Verify meter operation by measuring a known voltage. (2) Apply meter to circuit under test. (3) Return to the known live voltage again to ensure proper operation. · Never ground yourself when taking electrical measurements. · Connect the black common lead to ground or neutral before applying the red test lead to potential voltage. Disconnect the red test lead from the voltage first. · Always work with a partner. · When using the probes, keep fingers as far behind the probe tips as possible.

The display will show numerical values only for other functions. The main display is to be used to view units of measure for all other functions. Page 4 OPERATION: High Voltage Warning (HI-V) The meter beeps and lights an LED when > 30V AC/DC voltage is present through the test leads of the meter. This enhanced safety feature alerts the user that dangerous voltage is present across the leads even if the meter is set on an incorrect function or range. Note: This features does not work through the clamp head as the clamp is intended to only measure current. Auto/Manual Ranging Mode ( ) The meter defaults to autoranging mode when powered on. In this mode, the meter automatically selects the best range to display the measurement. By pressing the Range ( ) button on the meter, the manual range mode will override the auto-ranging feature of the meter. A ( ) appears in the upper left side of the display. Continue pressing the Range button until the desired range is obtained. Use this mode to lock in a specific range for repeated measurements. To return to the autoranging mode, either depress the Range button for greater than 1 second or turn the meter off and then back on again. Peak Max/Min Feature Peak function captures peak voltage in the VAC function and peak current in the AAC function. Both P+ and P- have 1 ms capture time. Set the meter to the desired function, press the "PEAK" button and apply the setup to the circuit. The P+ will be displayed. Press the "PEAK" button again to display the P-. Depress the peak button for >2 sec. to exit the peak feature. Note: If a more accurate peak measurement is required, then calibration should be performed. Depress the Peak button for >2 sec. until "CAL" appears in the display. The meter selfcalibrates to ±3% accuracy + 60 digits accuracy (400m/4VAC ranges unspecified). Max/Min Feature The Max records the maximum vaue measured over time while Min captures the minimum value measured over time. Press the Max/Min button to activate this feature and to toggle between Max, Min and Maxmin. "MAXMIN" displays the real time reading while still capturing max and min values over time. Depressing the max/min button for >2 sec. exits the mode. Note: To record max/min values over a time period >30 min, the Auto Power Off (APO) feature must be defeated. Data Hold Feature Press the Hold button on the side of the meter to toggle in and out of the data hold mode. "HOLD" appears in the upper left of the meter display when data hold is active. Use the data hold feature to lock a measurement reading on the display. Press the Hold button again to unlock the display and obtain a real-time reading. Page 5 Relative Mode ( ) (61-774 model only) This mode is used to zero out the display before measuring DC current. Press the " "button to subtract out the non-zero number. Then, measure the DC amps. Pressing the " " button again causes the " " to flash and the original offset number to be displayed. Depress the " " button for >2 sec. to exit this mode. Selectable Auto Power Off (APO) Feature The meter automatically powers itself down after about 30 minutes of no use. Press any button, and the meter will wake up and display the last reading taken before power down. This feature can be overridden by holding the Range ( ) button while turning the function switch from Off to any other position. When APO is defeated, the "APO" will be removed from the display. Turning the meter off will restore the APO default. Backlight Press the button in the middle of the meter to turn the backlight on and off. The green backlight will remain lit for about 4.5 minutes before it automatically turns off to conserve battery power. Also, the TightSightTM bottom display only lights while the meter is in the Amp function to minimize battery drain. Note: Backlight consumes 4x the battery power. 61 -774 40 0 10 00 AP AC O 0 A CO 10 M 20 30 V/ CA CA T. IV T. III 600 V MA 1000V 100 X 750 0V V 40 Backlight on in all functions.
