Your DVM68N is an auto-ranging professional digital multimeter with a 3 ¾ digit LCD display. It is ideally suited for
field, lab, shop, and home applications. By using the latest in IC and display technology to significantly reduce the
number of discrete internal components, the multimeter gives you superb measuring capability as well as the highest
possible reliability.
It is capable of performing functions:
DC Voltage
AC Current
Frequency
Also diodes and transistors (amplification hFE) can be tested.
1.1 Warning
Use extreme caution in the use of this device. Improper use of this device can result in injury or death. Follow all
safeguards suggested in this owner's manual in addition to normal safety precautions in dealing with electrical
circuits. Do not use this device if you are unfamiliar with electrical circuits and testing procedures.
Not for commercial or industrial use.
1.2 A word about safety
This multimeter is designed to ensure the safest operation possible. However, safe operation depends on you, the
operator. Make sure you follow these simple safety rules:
• Never apply a voltage to the multimeter that exceeds the limits given in the specifications. Never apply more than
1000V DC or 750V rms AC between an input jack and ground.
• Use extreme caution when working with voltages above 60V DC or 30V AC rms.
• Always discharge filter capacitors in the power supply circuit under test before you attach test leads.
• Never connect to a source of voltage when you select DCA, ACA, resistance measurement, continuity check or
capacitance function.
• Always turn off power and disconnect the test leads before you replace the batteries or fuse.
• Never operate the multimeter unless the battery cover is in place and fully closed.
When carrying out measurements on TV or switching power circuits, always remember that there may be high
amplitude voltages pulses at test points which can damage the meter.
