Warning Safety sheet .......... .......... .......... ........ ......... .......... .......... ........ ......... Read First Safety Information Understand and follow operating instructions carefully. Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.
CAUTION ˙ Disconnect the test leads from the test points before changing the position of the function rotary switch. ˙ Never connect a source of voltage with the function rotary switch in Ω,50V,100V,250V,500V,1000V position. ˙ Do not expose Meter to extremes in temperature or high humidity. ˙ Never set the meter in Ω,50V,100V,250V,500V,1000V function to measure the voltage of a power supply circuit in equipment that could result in damage the meter and the equipment under test.
The Meter Description Front Panel Illustration 1. LCD display ：4000 counts . 2. Push-buttons for features. 3. Rotary switch to turn the Power On or Off and to select a function. 4. Input Terminal for Ω function. 5. Input Terminal for V Insulation functions. 6. Common (Ground reference) Input Terminal for all functions.
Measuring ACV/DCV：Auto sense function Auto sense mode: The meter displays ACV or DCV whichever is higher (>0.3V). If the measured voltage is above 660Vac/dc, "> 660Vac/dc" will appear on the display.
Measuring Earth-Bond Resistance 1. Before starting the test : (a) The circuit under test must be completely de-energized. Check the fuse before testing. Connecting to an energized circuit while the test is active will blow the fuse. See Testing the fuse later in this manual. If the detected voltage is above 2V, ">2V" will appear on the display. In this condition, the test is inhibited. (b) Short the test leads before measurement, and press the blue button to compensate the probe resistance for <2Ω.
Measuring Insulation Resistance = 1. Before starting the test : The circuit under test must be completely de-energized. If the voltage detected is above 30V, ">30V" will appear on the display. In this condition, the test is inhibited. 2. Press the blue button to display insulation resistance or Leakage current during the test or when the test stops. 3. Lock mode: Press the Lock button to enter the Lock Mode. Then press TEST button to start the test.
Using the Compare function 1. Before starting the insulation test : Press the COMP button to select the compare value among 100kΩ,200kΩ,500kΩ,1MΩ,2MΩ,5MΩ,10MΩ,20MΩ, 50MΩ,100MΩ,200MΩ and 500MΩ. 2. If the measured value is greater than the selected compare value, the green Pass indicator will be turned on.
If the reading for DAR is bigger than 1.3 or PI is bigger than 2, it indicate a good insulation quality. When the measured resistance is higher than the maximum range, the screen will display "Err" symbol for PI/DAR value. TEST button : Press once to start/interrupt the PI /DAR test. Blue button : Press once during the PI/DAR test to display the time left of the test.
Using the Store function Store/Recall button : The screen will be flashing MEM symbol and the number of stored data twice when the Store/Recall button is pressed. 1. Press once to store the voltage value during voltage test 2. Press once to store the PI/ DAR, insulation or Earth-bond resistance value when the individual test is completed. 3. The memory is divided into five segments，each segments has 100 maximum data. The method to store the data is first in /first out when the memory is full.
Read the stored value of insulation test under RECALL mode Read the stored value of DAR test under RECALL mode Press the PI/DAR button ≧ 2 sec to choose the DAR function, and Press the Store/Recall button ≧ 2 sec to enter the RECALL mode.
Read the stored value of PI test under RECALL mode Press the PI/DAR button ≧2 sec to choose the PI function, and Press the Store/Recall button ≧2 sec to enter the RECALL mode. Auto Power Off (Battery Saver) Restore power by switching rotor or pressing any button. Auto Backlight The backlight is automatically turned on at dark environment. BUZZER The Meter beeps once for every valid key-press, and beeps twice for every invalid key-press.
Power-up options : Press button while turning meter on from OFF position. Lock button : display of the software version. Store button : Reset all stored data Battery and Fuse Replacement Refer to the following figure to replace fuse and the batteries : 2 Caution ˙ Use only a fuse with the amperage, interrupt, voltage, and speed rating specified. ˙Fuse rating : Fast, 315mA, 1000V, Min Interrupt Rating 10000A ˙ Replace the batteries as soon as the low batteries indicator "=" appears, to avoid false reading.
Specifications General Specifications Maximum voltage applied to any terminal : 600 V ac rms or dc. Display : 4000 counts. Polarity Indication : Automatic, positive implied, negative indicated.
