BTMETER BT-705A Signal Pick-up Inductive Clamp Lead, Measure Tach Range 600 RPM ~ 12000 RPM

PRODUCT DESCRIPTION

★【Important Note】This Signal Pickup needs to be used with multimeter or oscillograph for tach RPM measurement for vehicle engine. It’s recommend to use it with BTMETER BT-770K, BT-90K, BT-6688D automotive multimeter.

★【Great Companion to Automotive DMMs】 Features with standard 3/4 inch banana plugs, which means makes it compatible with most automotive meters that features with signal input.

★【Inductive Pickup Leads for BT-770K BT-90K】Perfectly work with BTMETER automotive multitester, such as: BT-770K, BT-90K, BT-6688D. To measure secondary end conductors of high voltage ignition coil spark .

★【Easy to Use】Clamp the spark plug wire with the mark ”→“ on the inductive pickup tool pointing to the spark plug for engine speed measurement.

★【Notice in Measurement】The distance between the spark plug and the clamp of the instrument must be less than 3.93 inch (10cm) during test, and the ignition frequency of the engine ignition system must be between 10Hz and 400Hz.

BTMETER BT-705A Inductive Signal Pick Up Clamp

• The signal pickup lead is professionally designed for adjustment and diagnosis of automotive engine, and it can be used with oscillograph or multitester to measure frequency or tach rpm.

• BT-705A pickup kit needs to work with digital multimeter features with signal input and capable of measuring parameters of vehicle engine systems.

• Adapting standard banana plug of 3/4 inch, inductive clamp is compatible with most multimeters with signal input functions. It work perfectly with BT-770K, BT-90K, BT-6688D automotive multitesters.

Features:

♦ Tach Measuring Range: 600RPM ~ 12000RPM

♦ Detection Mode: Magnetive Induction Measurement

♦ Applicable Engine: Spark Plug Igintion Gasoline Engine

♦ Detection Site: Secondary End Conductors of High Voltage Ignition Coil

Operating Instruction

1. Connect the clamp of the instrument to a spark plug wire with the mark ”→ “ on the instrument pointing to the spark plug.

2. Connect the plugs of the instrument to the input terminals of the automotive meter (The black plug of this instrument should be connect to “COM” jack of the automotive meter)

3. Set the automotive meter in corresponding measuring range.

4. Read the valve on the LCD display. If no reading is received, unhook the clamp, turn it over and connect again.

It works!

But the instructions are wrong. It must be connected in the multimeter to mV scale, not to mA scale.

At this price, this probably as good as it gets

I evaluated this clamp meter at my lab for DC currents only. All measurements were taken
at 10 amps or less.

Comments:
In the past twenty years, "safety shrouded" test leads have become the norm.

This is understandable in AC or DC volts or in any circuit with high voltage potentials.
In this particular application, the safety shrouded leads are not necessary, and make it
difficult to connect to older multimeters.

Why are they not needed? You are not opening the circuit to take a current measurement,

and the clamp output is only 1mv/AMP . So in the worse case scenario if you were measuring 600 AMPS

(the maximum current the device can handle) the output from the clamp will be 600mv only!

Second comment:

The manual enclosed was for the wrong model!

It tells you to set meter to microamp function, this is wrong!

Set dvm to DC millivolt range (which one depends on how much current you expect)

comment 3:

They tell you to press "REL" key on dvm, don't do this unless you are measuring small currents (< 2.5 A)

My offset reading was -0.133 Amps (with zero current input)

If you press "REL" you will add 0.133 AMPS (in my case) to all readings, it will ONLY help you for small
currents. For larger currents, it will make the readings worse.

Most please that buy a clamp meter, do so to measure large currents, that is probably for situation.

So, do NOT press the "REL" key

comment 4:

Great value for the money, errors were less than 4.5% if you keep it between 3A and 10A

No measurements were taken above 10A, I will leave that to someone else to do, my lab
is very limited. (NO AC measurements were taken also)

I don't see how I can do better than this, considering how little money I payed!!
