Frequently Asked Questions - TT-1P Electronics International
How do I replace the battery?
To replace the battery, turn off the meter and remove the back cover. Remove the old 9V battery and insert a new one observing polarity. Replace the cover securely.
What is the maximum voltage I can measure?
The TT-1P can measure up to 600V AC/DC. Do not exceed this limit to avoid damage or injury.
How accurate is the device?
DC voltage accuracy is ±0.5% of reading + 2 digits. AC accuracy is ±1.2% of reading + 3 digits. Resistance accuracy varies by range.
Can I measure temperature?
No, the TT-1P does not have a temperature measurement function. It measures voltage, current, resistance, diode, and continuity.
Why does the display show 'OL'?
'OL' stands for Over Load. It indicates the measured value exceeds the selected range. Switch to a higher range if available.
How do I use the continuity test?
Set the dial to the continuity symbol (usually a sound wave). Connect the probes across the circuit. A continuous beep indicates a complete circuit (low resistance).
The device doesn't turn on. What should I do?
First, ensure the battery is installed correctly and has sufficient charge. Replace with a fresh 9V battery if needed. Also check the fuse (if equipped) and contacts.
Is the device auto-ranging?
No, the TT-1P is manual-ranging. You must select the appropriate range using the rotary dial for each measurement type.
What type of probes are included?
The device comes with a pair of standard test leads with shrouded banana plugs and pointed tips. They are rated for CAT II 600V.
How do I clean the device?
Wipe the housing with a soft, dry cloth. Do not use any abrasive cleaners or solvents. Keep the probes clean for accurate readings.
