BM89 is a kind of portable clamp meter , it can be used to measure DC voltage and current,AC voltage and current,TRUE RMS,resistance,frequency,continuity,temperature, forward voltage drop of diode.capcitance measurement range extended to 10mF,more fast to measure large capacitance.This product is excellent tool for electricity measurement with its compact structure,easy to be operated ,convinent to be carried,especially suitable for the measurement of refrigeration equipment,electrical repair and large current situations,the inrush current test function is especially suitable for the measurement of starting current.
Features:1.The meter is based on CMOS large scale IC and can automatically
changed measuring range for measurement of AC/DC voltage, AC
current, resistance, frequency and capacity, which makes the meter
easy to be used.
2.Display mode: Display by LCD.
3.Maximum display: 3999 or 9999(when measuring capacitance
and frequency)
4.Maximum span of jaw: 32mm.
5.Data Hold:Short time pressing"DH" key can maintain the current readings, release the button to cancel data hold function. In AC voltage and current measurement function,press the key for more than 2 seconds ,the INR measurement of inrush voltage and current will be displayed.
6.Auto negative polarity indication: Displaying “-”.
7. Lack of battery power: Displaying “ ”.
8 .Auto power OFF
After turning on the instrument and without operating the function
switch or pressing any button, the instrument will automatically enter
into sleep mode after 10 minutes,to save battery power.when it is in the sleep mode you can press the SELECT key to wake up the instrument. If you don't need the automatic sleep mode, you should hold down the DH key to turn on the instrument, and then the symbol" " will not be display on the LCD.
