Sealey TA101 Instructions Manual

1.1. PERSONAL PRECAUTIONS

 When using the analyser, please observe all normal safety rules concerning:
Protection against the dangers of electric current.
Protection of the analyser against misuse.
 Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, these must be replaced with genuine
Sealey leads with the same electronic ratings. Failure to do so will invalidate the warranty.

 DO NOT use leads if damaged or if the wire is bared in any way.

1.2. GENERAL SAFETY INSTRUCTIONS

 Familiarise yourself with the application and limitations of the analyser as well as the potential hazards. IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
 When the analyser is linked to a measurement circuit, do not touch unused analyser terminals.
 When the scale of the value to be measured is unknown set the selector to the highest range available.
 Before rotating the range selector to change functions, disconnect test leads from the circuit under test.
 WARNING! Never perform resistance measurements on live circuits. Only measure on disconnected circuits.
 Always be careful when working with voltages above 60V DC or 30V AC. Keep fingers behind the probe barriers whilst measuring.
 When not in use, store the analyser carefully in a safe, dry, childproof location. Storage temperature range -10°C to 50°C.
 Never apply voltage or current to the analyser that exceeds the specified maximum.
 WARNING! Do not make current measurements on the 10A scale for longer than 10 seconds in every 15 minutes. Exceeding 10 seconds may cause damage

to the analyser and test leads.

4. OPERATION

 WARNING! Ensure that you read, understand and apply the safety and operational instructions before connecting the analyser. Only when you are sure
that you understand the procedures is it safe to proceed with testing.
 WARNING! Risk of electrocution. High voltage circuits, both AC and DC are very dangerous and should be measured with great care.
Operating temperature range 0°C to 40°C.

Remember to turn off analyser when measurement is completed.
Note: If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Select a higher range.
Note: On some low AC and DC ranges, with the test leads not connected to a device, the display may show a random fluctuating reading. This is

normal and is caused by the high input sensitivity. The reading will stabilise and give a correct measurement when connected to a circuit.

4.1. Data Hold Button

4.1.1. The data hold function allows the analyser to freeze a measurement reading for later reference.

4.1.2. Press the data hold button once to freeze the reading in the display. The indicator “H” will appear in the display.

4.1.3. Press the data hold button again to return to normal operation.

4.2. AC/DC Voltage Measurement

4.2.1. Insert the black test lead into the negative COM socket and the red test lead into the positive VΩRPM socket.

4.2.2. Turn the function dial to the voltage setting and press the function selection button to select AC or DC as required.

4.2.3. Connect the test leads to the circuit under test and read the voltage on the display.

4.2.4. For DC voltage, the polarity of the red test lead will be displayed as well as the value.

4.3. DC Current Measurement
 WARNING! Do not make current measurements at 10A for longer than 10 seconds in every 15 minutes. Exceeding this may cause damage to
the analyser and test leads.

4.3.1. Insert the black test lead into the negative COM socket, and the red test lead into the positive µAmA socket (or the positive 10A socket for currents from
326mA to 10A).

4.3.2. Turn the function dial to the appropriate setting as required (see ranges above). If the current range to be measured is not known, set to the highest
range setting, and then select to the correct range when the first reading is taken, until satisfactory resolution is obtained. Press the function selection
button to select AC or DC as required.

4.3.3. Connect the test leads in series with the circuit under test and read the current on the display.

4.3.4. For DC current, the polarity of the red test lead will be displayed as well as the value.
