DVM860BL – DIGITAL MULTIMETER
1. Introduction
At the end of its life cycle, dispose of this product in accordance with local and national disposal
regulations. Read the manual thoroughly before bringing this device into service
Thank you for buying the ! Use this device to measure and test: AC & DC voltage & current (also with DVM860BL
optional clamp ), resistance, temperature, batteries, diodes, continuity and transistors. AC97
2. Safety
The is developed in accordance with IEC1010-1 concerning safety requirements for electrical measuring DVM860BL
instruments with an overvoltage category (CAT III) 600V and pollution 2. Respect these safety prescriptions:
• Protect yourself against electroshocks.
• Do not use this device for any other application than those described in this manual.
• Make sure the device was not damaged in transit.
• Make sure the insulation of the test leads is not damaged and/or the wire itself is not exposed.
• Full compliance with safety standards can only be guaranteed if the device is used with the supplied test leads. If
necessary, they should be replaced with identical leads or leads with identical electric ratings. All test leads should
be in good working order.
• Select the right input jack, function and range before use.
• Never exceed the specified limit values for the various measurement ranges.
• Do not touch unused terminals when the meter is connected to a circuit.
• Place the range selector in the highest position if the value to be measured is unknown beforehand.
• Do not measure voltages > 600V above earth ground.
• Exercise extreme caution when working with voltages in excess of 60Vdc or 30Vrms AC. Keep your fingers behind
the probe barriers while using the device.
• Do not connect the leads to a voltage source while the function switch is in one of the following modes: current,
resistance, temperature, battery, diode, transistor or continuity.
• Disconnect all test leads from the circuit to be tested prior to selecting a different function or range.
• Do not use the meter in dusty environments or in the presence of flammable gases and steam.
• Have the device checked by a qualified technician in case of malfunction.
• Never use the meter if the back panel is not in place and firmly fixed.
• Do not use or store the device in areas exposed to direct sunlight, high temperatures or high humidity.

4. Maintenance
• Do not remove the back cover while a voltage is being applied. Only a qualified technician should handle repairs.
•
Always disconnect the test leads from all current sources before opening the meter.
• Replace the batteries when the symbol is displayed.
• Replace blown fuses with an identical one or a fuse with identical voltage and current ratings: F 200mA/250V
(quick-acting).
• Use a damp cloth and a mild detergent to clean the device. Never apply abrasives or solvents to the meter
• Place the power switch in the OFF position when the device is not being used
• Remove the batteries to keep them from leaking if the device is to be stored for a long time.
