Frequently Asked Questions - TB 312 Testboy

How to measure DC voltage with the TB 312?

Set the selector to the V range (mV or V). Connect the black lead to COM, the red lead to V/mV/Ω. Apply the probes to the circuit. Read the value on the display. Polarity is shown automatically.

What is the procedure for measuring a current above 500 mA?

For a current > 500 mA, always use the 10 A connector (left). Connect the red lead to the 10 A jack and the black lead to COM. Set the selector to the corresponding A range. Caution: do not exceed 10 seconds of measurement, then let cool for 15 minutes.

How to test a diode with the TB 312?

Set the selector to the diode position (symbol ➞). Connect the red lead to V/mV/Ω and the black lead to COM. Connect the red probe to the anode and the black probe to the cathode. The display shows the diode's forward voltage.

How to perform a continuity test?

Set the selector to Ω/°). Press SELECT to switch to continuity mode. Connect the leads as for resistance measurement. A beep sounds if the resistance is less than 60 Ω. Make sure the circuit is de-energized.

How to replace the multimeter's batteries?

Disconnect the test leads. Open the battery compartment on the back (unscrew the screws under the folding stand). Replace the 6 AAA 1.5V batteries, observing polarity. Close the compartment.

How to replace a fuse?

Disconnect the leads. Open the battery compartment. Remove the protective cover of the relevant fuse. Replace it with an identical fuse (F 500 mA/1000 V or F 10 A/1000 V fast). Replace the cover and close.

How to connect the TB 312 to a PC?

Install the software from the CD. Connect the USB cable. Press and hold HOLD until 'PCLINK' appears. In the software, select the virtual COM port (check in Device Manager) and click Connect.

What does the 'AUTO' symbol on the display mean?

The 'AUTO' symbol indicates that the automatic range selection is active. You can switch to manual mode by pressing RANGE.

What are the safety precautions before using the device?

Follow the five safety rules: disconnect, prevent restart, verify absence of voltage, ground, and cover live parts. Use only CAT III 1000 V leads. Do not exceed the maximum ranges.

How to clean the multimeter?

Use a damp cloth with a mild household detergent. Never use solvents or abrasive products. Ensure the device is off and disconnected before cleaning.

In order to ensure safe and reliable operation using the instrument, you must always observe the safety instructions, warnings and the information contained in the section "Intended use".

WARNING

Please observe the following information before using the instrument:

Do not operate the instrument anywhere near electrical welders, induction heaters or other electromagnetic fields.
Further to abrupt temperature fluctuation, the instrument must be allowed to adjust to the new ambient temperature for approx. 30 minutes before using it, in order to stabilise the IR sensor.
Do not expose the instrument to high temperatures for a long period of time.
Avoid dusty and humid environments.
Measuring instruments and their accessories are not toys, and must be kept out of the reach of children!
In industrial facilities, the accident prevention regulations for electrical systems and equipment, established by the employer's liability insurance association, must be observed.

Please observe the five safety rules:

1 Disconnect
2 Ensure that the instrument cannot be switched back on again
3 Ensure isolation from the power supply (check that there is no voltage on both poles)
4 Earth and short-circuit
5 Cover adjacent live parts

Intended use

The instrument is intended strictly for use in applications described in the operating instructions. Any other usage is considered improper and forbidden, and can result in accidents or the destruction of the instrument. Any such application will result in the immediate expiry of all guarantee and warranty claims on the part of the operator against the manufacturer.

Remove the batteries if the instrument is not in use for a long period of time, in order to protect the instrument from damage.

We assume no liability for damages to property or personal injury caused by improper handling or failure to observe the safety instructions. Any warranty claim expires in such cases. An exclamation mark in a triangle indicates safety notices in the operating instructions. Read the instructions completely before beginning the initial commissioning.

Cleaning

Use a damp cloth and mild household detergent to clean the instrument should it become soiled through daily use. Never use aggressive cleaning agents or solvents to clean the instrument.

Changing the batteries

Change the batteries when the battery icon is displayed. Remove the test leads from the instrument before changing the batteries!

Remove the two screws on the rear of the instrument below the fold-down pedestal, open the battery compartment and remove the spent batteries. Insert new batteries (6 x 1.5 V AAA Micro). Ensure that the polarity is correct. Replace battery compartment and screw tight.

Only use the batteries specified!

Batteries must not be disposed of with normal domestic waste!

Observe the statutory regulations pertaining to disposal!

Changing the fuse

When you need to change the fuse, first remove the test leads from the instrument and remove the battery compartment's two screws on the rear behind the fold-down pedestal. Carefully remove the battery compartment lid, lift off the relevant protective cap of the fuse that is to be changed and replace the defective fuse with one of the same sort (F 10 A / 1000 V or F 500 mA / 1000 V fuse). Replace the protective cap and retighten the screws of the battery compartment.

Only use fuses with the values specified!
