Page 4: Summary
1 sUMMary DT-16/DT-18 is a portable notebook autoranging digital multimeter (DT-16 is 3 1/2 and DT-18 is 3 3/4). It is a full - featured, stable performance, high precision, low power consumption and novel structure, safe and reliable multimeter, and it can be used to measure AC/DC voltage, frequency, duty cycle, resistance, ca pacitance, diode forward voltage drop and on-off test. - Page 5 User's Guide of Digital Mini Multimeters DT-16/DT-18 display. 2. When using the probe, your finger must be placed after the probe finger gDTrd ring. 3. Do not apply voltage more than 500V between the meter terminal and ground to prevent electrical shock and damage to the meter.

User's Guide of Digital Mini Multimeters DT-16/DT-18 ⑵ Put rotary switch to DCV files. ⑶ Please read the measured voltage value directly from the display. ⑷ The LCD will display negative readings if exchange the probes. Cautions: Don’t input the voltage above 500V. It is possible to measure higher voltage but it will damage the instrument. -
