This meter is for indoor use, altitude up to 2,000 m. Avoid working alone. Use the meter only as specified in this manual; Otherwise, the protection provided by the meter may be impaired. Never measure Voltage while the test leads are inserted into the current input terminals. Do not use the meter if it looks damaged. Inspect the leads for damaged insulation or exposed metal. Check test lead continuity. Replace damaged leads. Disconnect the power and discharge all high-voltage capacitors before testing in the resistance, continuity, and diode function. Be cautions when working above 60V DC or 30V AC RMS. Such voltages may cause a shock hazard. When making measurements, keep your fingers behind the finger guards on the probe. Select the proper function and range for your measurement. To avoid damaging the meter, disconnect the test leads from test points before changing functions. CE requirement: Under the influence of R.F field according to standard, the supplied test leads will pick up induced noise. To have better shielding effect, a short-twisted lead shouid be used. The standard of test requirement shows below. 1. IEC 801-2: That is ESD (electro-static discharge) test. 2. IEC 801-3: This is RFI (Radio Frequency Interference) test. Condition: 27~500MHz, signal intensity is 3Volts per meter. 3. IEC 801-4: This is EFT (electrical fast transient) test. 4. EN 55011: This is EMI test. The meter is safety-certified in compliance with EN61010 (IEC 1010-1, IEC 1010-2-031) Installation Category III GOOV and CAT II 1000V. in order to maintain its insulation properties, please be sure to use with the standard or compatible test probes.A UNIQUE MULTIMETER | 0 INTRODUCTION This series product has two models. Both of meters are TRUE-RMS measurement. One combines AC/DC voltage and current, frequency measurements etc. It is high accuracy and economical choice. The other one offers the combination of TRUE-RMS measurements (AC+DC TRUE RMS), Frequency, Duty Cycle and Pulse width measurements. Conductance measurement helps detect the insulation of conductor and ground. A unique function of Square wave out, let user have free space for application. For instance, PWM (pulse width modulation) out, adjustable voltage control, timer to control circuit, synchronic clock (baud rate generator) etc,. That is a free-for-all application function. Frequency measurement helps detect the presence of harmonics in neutral conductors and determine whether they are the result of unbalanced phases or non-linear loads. The MULTIMETER is shown in Figure 1. This meter has a lot of functions there are shown below. A unique Square Wave out function. Resolution of display adjustable: 4,000/ 40,000 counts. TRUE RMS measurement for non-linear and traditional loads. Both Current and Voltage can do AC+DC measurement. Bi-directional 1 ms Peak Hold feature to capture glitch. Many combinations of Dual display for easily analyzing components of Current or Voltage signal. 10 MHz frequency counter. High impedance measurement (40 nS / 100 GQ). dBm measurement can select 20 types of reference impedance. K-type temperature measurement.

The average reading is useful for smoothing out unstable or changing inputs, estimating the percentage of time a circuit is operated, or verifying circuit performance. The operational procedures are described below. 1) Press "MAX e MIN" for more than 1 second to enter the dynamic recording. The present value is stored to memories of maximum, minimum and average. MAX AVG MIN annunicator will be on. 2) Press this button for more than 1 second to exit recording mode. 3) Press this button momentarily to cycle through maximum, minimum, average and present readings. The MAX, MIN, AVG or MAX AVG MIN annunciator turns on respectively to indicate which value is being displayed. See Figure 6. 4) The beeper sounds when a new maximum or minimum value is recorded. 5) If an overload is recorded the averaging function will stop. An average value becomes " OL "(overload). 6) In dynamic recording, the auto power off feature is disabled. and the QOFF will be tumed off. 7) Selecting dynamic recording in auto range, it will record the value of MAX, MIN or AVG for different ranges. -17-8) The recording speed of dynamic recording is about 100 milli-seconds (0.1 second). 9) The average value is the true average of all measured values taken since the recording mode was entered. 10) The secondary digits show the relative stamping time for MAX, MIN, AVG reading. 41) The unit of relative time is second, and the maximum display is 99,999 sec. lose pong! =" afto PUSH go0e3 (HBG @etreoueu * Seoantereel PUSH PUSH (QH)LSEC Figure 6.

Above this temperature, toxic gas might be emitted. Do not immerse this thermocouple in liquids. For best results, use the thermocouple probe designed for each application (i.e., an immersion probe for liquid or gel, an air probe for air measurements, etc), follow the measuring techniques below. @ Clean the measurement surface and make sure the probe is attached securely to the surface. @ When measuring above ambient temperatures, move the thermocouple on the surface until you get the highest temperature reading. @ When measuring below ambient temperatures, move the thermocouple on the surface until you get the lowest temperature reading. 1) Turn the rotary switch tothe "Temp OUT "range. 2) Plug the adapter (DP-26) with thermocouple probe (DP-27) into "Temp" (the plus side) and "COM" (the minus side) terminal. 3) Press "DUAL " button to toggle between C (Celsius) and F (Fahrenheit) on primary display. 4) Attach the thermocouple to the heated source. 5) Read the display. CAUTION: Do not sharply bend the thermocouple leads. Repeatedly bending the leads can break them. NOTE : DP-27 is K-type thermocouple probe.

If the instrument still does not work, double check operating procedure as described in this instruction manual. When servicing, use specified replacement parts only. WARNING To avoid electrical shock or damage to the meter, do not get water inside the case. Remove the test leads and any input signals before opening the case. 0 BATTERY REPLACEMENT The meter is powered by a single 9V battery, with NEDA1604, JISOOSP, IEC6F22 carbon-zinc or alkaline battery. Replace battery if the low battery sign (Z=)) is displayed and flashes. Use the following procedures to replace the battery: 1. Using the rotary switch to tum the meter off, and disconnect the test leads from external equipment. 2. Loosen 3 screws on bottom cover, pull up and move the cover. See Figure 34. 3. Replace the defective battery. 4. Reverse the procedure of opening cover to close the bottom cover. C] FUSE REPLACEMENT Referring to Figure 34 and 35, use the following procedure to examine or replace the fuses of the meter: 1. Perform steps 1 to 2 of battery replacement procedure. 2. Lift the circuit board as shown in Figure 35. 3. Remove the defective fuse by gently prying one end of the fuse loose and sliding the fuse out of the fuse bracket. 4. install a new fuse of the same size and rating. Make sure the new fuse is centered in the fuse holder. 5. Ensure that the rotary switch on top case and the switch on the circuit board are in the OFF position. 6. Then re-fasten the circuit board and the bottom cover respectively. -62- 0 CLEANING To clean the instrument, use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may leak into the cabinet and cause damage. Do not use chemicals containing benzine, benzene, toluene, xylene, acetone or similar solvents.
