User's Guide 800 Amp Clamp Meters EX710 AC Clamp meter EX730 AC/DC True RMS Clamp meter
Introduction Congratulations on your purchase of the EX710 or EX730 Clamp DMM. Careful use of this meter will provide many years of reliable service. Safety International Safety Symbols This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information.
CAUTIONS • Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. • Always remove the test leads before replacing the battery or fuses. • Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use. • Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.

Operation NOTES: Read and understand all Warning and Caution statements in this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use. AC/DC Current Measurements (DC Current on Model EX730 only) WARNING: Ensure that the test leads are disconnected from the meter before making current clamp measurements. 1. Set the Function switch to the 800A, 400A, or 40A range. If the approx.
Resistance Measurements 1. Insert the black test lead into the negative COM terminal and the red test lead into the V·Ω·CAP·TEMP·Hz· positive terminal. 2. Set the function switch to the Ω position. 3. Touch the test probe tips across the circuit or component under test. 4. Read the resistance on the LCD display. Capacitance Measurements WARNING: To avoid electric shock, discharge the capacitor under test before measuring. 1. Set the function switch to the CAP position. 2.
Temperature Measurements(Model EX730 only) 1. Set the function switch to the TEMP position. 2. Insert the Temperature Probe into the negative COM and the V·Ω·CAP·TEMP·Hz· positive jacks, observing polarity. 3. Touch the Temperature Probe head to the device under test. Continue to touch the part under test with the probe until the reading stabilizes. 4. Read the temperature on the display. The digital reading will indicate the proper decimal point and value. 5. Use the MODE button to select F or C.
Data Hold To freeze the LCD reading, press the HOLD button. While data hold is active, the HOLD icon appears on the LCD. Press the HOLD button again to return to normal operation. DC ZERO (Relative) (EX730 only) The DC ZERO is a relative feature and can be used in any function. 1. Press the DC ZERO button to zero the display. “ZERO” will appear in the display. The displayed reading is now the actual value less the stored “zero” value. 2. Press the DC ZERO button to view the stored value.
