User's Guide True RMS Industrial Multimeter
Introduction Congratulations on your purchase the True RMS Autoranging Multimeter. This meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Duty Cycle, Diode Test, and Continuity plus Thermocouple Temperature. It features a waterproof, rugged design for heavy duty use. Proper use and care of this meter will provide many years of reliable service.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This meter includes a Bluetooth module, it can easily transfer the data in display to your smartphone. How to Setup 1.
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. • Use great care when making measurements if the voltages are greater than 25 VAC rms or 35 VDC. These voltages are considered a shock hazard. • Warning! This is a class A equipment.
SAFETY INSTRUCTIONS This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation. 1.
Controls and Jacks 1. 50,000 count LCD 2. MAX/MIN button 3. RANGE button 4. MODE button 5. Function switch 6. mA, µA and 10A input jacks 7. Bluetooth LED indicator 8. RELATIVE and Bluetooth Power button 9. PEAK button 10. HOLD and (Backlight) button 11. Positive input jack 12. COM input jack Note: Tilt stand and battery compartment are on rear of unit.
Operating Instructions WARNING: Risk of electrocution. High‐voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. 2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range. AC/DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.
AC/DC CURRENT MEASUREMENTS CAUTION: Do not make 20A current measurements for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert black test lead banana plug into the negative COM jack. 2. For current measurements up to 5000µA DC, set the function switch to the µA position and insert the red test lead banana plug into the µA/mA jack. 3.
CONTINUITY CHECK WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them. 1. Rotate the function switch to the Ω position. 2. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive Ω jack. 3.Press the MODE button to indicate“ " on the display 4. Touch the test probe tips to the circuit or wire you wish to check. 5.
THERMOCOUPLE TEMPERATURE MEASUREMENTS 1. Rotate the function switch to the TYPE K position. 2. Insert the Temperature Probe into the input jacks, making sure to observe the correct polarity. 3. Press the MODE button to indicate “ºF” or “ºC” 4. Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes. 5. Read the temperature in the display. Note: The temperature probe is fitted with a type K mini connector.
AUTORANGING/MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into AutoRanging. 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. Press the RANGE key. The “AUTO” display indicator will turn off. 2. Press the RANGE key to step through the available ranges until you select the range you want. 3.
Relative mode The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current, etc. can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value and the measured value. 1. Perform the measurement as described in the operating instructions. 2. Press and Hold the REL button to store the reading in the display and the "REL" indicator will appear on the display. 3.
Maintenance WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and fastened securely. This MultiMeter is designed to provide years of dependable service, if the following care instructions are performed: 1. KEEP THE METER DRY. If it gets wet, wipe it off. 2.
REPLACING THE FUSES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the meter cover. 1. Disconnect the test leads from the meter. 2. Remove the battery cover (two “B” screws) and the battery. 3. Remove the six “A” screws securing the rear cover. 4. Gently remove the old fuse and install the new fuse into the holder. 5. Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 600 mA range 10A/1000V fast blow for the 10A range 6.
