INTRODUCTION

Assark 85D is a multi-purpose true-RMS digital multimeter that can automatically select the appropriate function and range according to the input measurement signals for easy, fast, and convenient slectrical measuring. This high-performance Meter is equipped with a 6000-count LCD display to give clear and accurate readings. Itis designed to meet safety standard [EC61010-1 CAT Ill 600V, and provides overload protection on all ranges to ensure safe and reliable operation.
“This battery-powered Meter is expert in meastring AC/DC voltage, AC/DC current, resistance, capacitance, testing diode and continuity, and tracing live wires. With a lot of practical features, such as auto power off, NCV (Non-Contact Voltage) detector, backlight, and built-in torch, it is an ideal entry-level tool for lab, schoal, factory, and home use.

SAFETY NOTES

The Meter conforms to [EC61010-1 CAT Ill 600V safety standard. Please read all safety information and allinstructions carefully before you use the Meter. 1. Limit operation to the specified measurement category, voltage, or amperage. ratings. Do not apply more than the rated voltage, between the terminals or between each terminal and earth ground, 2. The safety voltage is not higher than 36V. Before measuring voltage higher than 36V DC or 25V AC, check the connection and insulation of test leads to avoid electric shock. When the input voltage (AC or DC) is higher than 24V, the high voltage warning symbol 4

wil appear on the display. Remove test leads from the Meter before changing function mode or range. Use the correct terminals, function, and range for measurements. Install the batteries and lock the battery door before operating the Meter. To avoid electic shock, injury, or damage to the Meter, disconnect circuit power and discharge all high-votage capacitors before testing resistance, continuity, diodes, or capacitance. Turn off the power and remove test leads from the Meter before replacing the batteries or fuse. Always adhere to local and national safety codes. Use personal protective ‘equipment (such as rubber insulating gloves, goggles, flame-resistant protective clothing etc.) to prevent shock and arc blast injury where hazardous live conductors are exposed. 9. Always use probes, test leads, and accessories that have the same. measurement category, voltage, and amperage ratings as the Meter. 10. Do not use the Meter around explosive gas, vapor, o in damp or wet environments.

Do not expose the Meter to magnetic fields, extreme heat, or expose to direct sunlight for long periods of time. 12. Do not use the Meter with damaged probes, test leads, and accessories o after the Meter malfunctions or is dropped or damaged in any manner, please contact our customer service for a replacement.

AAWARNING: To prevent possible electric shock, fire, or personal injury, do not use data hold mode to determine if a circuit i live or measure unknown voltage in a circuit. When data hold mode is turned on, the LCD screen will keep original data even you measure a different voltage.

IV. OPERATING INSTRUCTIONS

Always check the battery status before using the Meter, select the correct measured range according to your needs. If the Meter s out of power, “ea” will appear on the display. Please kindly note the sign “4¢ beside the terminas, it ‘warns that test voltage and current cannot excaed the specified value in this manual or on the product. * AUTO range mode: Can be used for measuring resistance, continuity, DC/AC voltage, and DC/AC current. « Manual mode: You can manually change the measurement mode by pressing the “FUNC” button, which can measure DC/AC voltage, continuity (6002, diode, and capacitance.

1. DC/AC Voltage Messuremen

1.1 According to your actual reqirements, select DC or AC voltage measurement mode under AUTO or Manual mode 1.2 Connect the test lads across to the tested circuit, the voltage and polarity of the red test lead will show on the display: 1.3 Insert the biack test lead into “COM” jack and red test lead into “J8″ jack. 1.4 Read measurement results on the display.
2 Nots <1 “OL” shows on the screen, it means “over range”. – When measuring a high voltage (above 220V), use personal protective ‘equipment to prevent shock and arc blast injury where hazardous ive conductors are exposed.

2. DC/AC Current Measurement

2.1 Insert the red test lead into “mA/A” jack, the Meter defauits to DC current measurement mode.
2.2 Short press the “FUNC button to choose AC current measurement mode. if needed.
2.3 Insert the black test lead into “COM” jack, and the red test lead into “MA/A” jack.
2.4 Connect the Meter in-series in the circuit using the test leads.
25 Read measurement results on the display.
2 Nots – Before connecting the Meter in the circuit (using the test leads), you should turm off the power of the circuit first, and then check if the input terminal and range/mode function wel. Do not use the current jack (“mA/A”) to measure avoltage.

– The maximum measuring current is 10A.

The Meter alarms when exceading the maximum measuring range. Overload input or wrong operation will blow the fuse. – When measuring a large current (above 5A), continuous measurement vl cause heat in the circult, affect measurement accuracy and even damage the Meter. Measuring time shall not exceed 10 seconds, and please allow the. Meter to recover for more than 15 minutes before the next measurement,
