Crenova 6016A Operating Manual

Operating Manual of Crenova 6016A Clamp Digital Multimeter

I. Overview

Crenova 6016A is a battery-driven 3 1/2 digital clamp meter for automatic range conversion which is
characterized by stable performance and high reliability. This meter applies 16mm word height LCD with
distinct readings, and features maximum hold, data hold and automatic on-off function.

This clamp meter can be used for measuring parameters such as DC voltage, AC voltage, resistance,
diode and on-off test. The complete meter is cored by dual integral A/D conversion of large scale
integrated circuit and features automatic range conversion function. It is a high-performance meter well
received by lab, factory, radio amateur and family.

Warning: before using the clamp meter, please read through “Safety Precautions”.

III. Safety precautions
Please note “warning sign and warning words”. It means cases or behavior which may pose
danger to user or cause damage to the clamp meter or device under test.

This meter is strictly in line with GB4793 Safety Requirements on Electronic Measuring Instrument,
IEC61010 and IEC1010-2-032 safety standard. It complies with safety standard for double insulation,
over-voltage CAT III 300V and pollution class 2.
Before use, please read through the operating manual.

1.When voltage above 30V, AC power line with inductive load is measured. When AC power line during
electric fluctuation is measured, please be cautious of electric shock.

2.Before measuring, check if the measurement function switch is at correct position. Check test leads for

reliable contact, correct connection and good insulation to avoid electric shock.

3.Clamp meter only meets safety standard when used with its supporting test leads. When test lead line is

damaged, please replace with lead line of the same model or the same electric specification.

4.Do not replace the battery inside with other non-confirmed or non-recognized one. Use battery of the
same model or electric specification only. Before replacing, the test lead must be away from the
measurement point and make sure the input end has no signal.

5.When do electrical measurements, human body should have no direct contact with earth. Do not touch

any metal terminal, output terminal or lead clamp which have exposed ground potential.

6.Do not store or use it in high temperature, high humidity, inflammable, explosive environment or high

magnetic field.

7.Measure limit voltage which is beyond allowed range will cause damage to the clamp meter and injury

to operator. Allowable limit voltage is indicated on the surface of clamp meter. Do not measure input
signal which beyond this standard so as to prevent electric shock or damage to the clamp meter.

8.Do not apply 600V above voltage between clamp meter terminal and earth so as to prevent electric

shock or damage to the clamp meter.

9.Do not attempt to calibrate or repair the clamp meter. When necessary, it should be done by personnel

with specialized training or qualification.

10.When measuring, function/range selection switch must be at correct range gear. When shifting

function/range selection switch, please disconnect the line of test lead from the object under test, and

make sure the input end has no signal input. Do not shift function/range selection switch during

measurement.

11.When LCD shows “ ”, please replace battery in time to make sure measurement accuracy.

12.Do not change clamp meter circuit without permission, so as to prevent damage to clamp meter or

safety risk.

VII. Key functions and auto power-off

⑴ SELECT： Press the button to select indicated measurement function when there are two or more

measurement functions on the same gear. It shifts between diode and buzzer measurements.

⑵ RANGE: The meter is in automatic range when starts up, press the “RANGE” button to activate

manual range mode. In the mode of manual range, each press lets the meter skip to the previous shift.
When it goes to the highest shift, it goes back to the lowest shift automatically. The procedure
repeats again in the same order. Press the “RANGE” button over 2 seconds, it will exit from manual
range measurement mode and shift to automatic range measurement mode.

⑶ HOLD:Press the “HOLD” button, the measurement value showed on the screen will be locked.

Press this button again, it will unlock and enter the state of regular measurement.

⑷ MAX ： Press the “MAX” button, the display screen will show maximum value of the whole

measurement process automatically. Press this button again, it will cancel maximum reading hold
status and enter the state of regular measurement.

⑸ Auto power-off function: In measurement process, if function button or function/range selection

switch has no operation within 15 minutes, the meter will “power-off automatically”. In the mode
of auto power-off, press function button (valid operation) or rotate function/range selection switch,
the meter will “power on automatically” and enter the measurement mode. Press and hold
“HOLD” button when start up, the auto power-off function will be canceled.

Note: “Auto power off” refers to a dormant state. In dormant mode, small current (about 5μA)

will be consumed. If it will not be used for a long time, please cut off power and take the battery out.

⑹ Buzzer: Press any one of functional buttons at any gear, if the button is effective, the buzzer will

beep. (2/20A buzzer will make no sound , and keep silence if the operation is invalid.) About 1
