1. Introduction
Thank you for purchasing an OAKTON
®
TEMP Acorn Meter. These economical,
microprocessor-based meters are available in three models:
• the Acorn TEMP 4 uses a series 400 thermistor temperature sensor
• the Acorn TEMP 5 uses a 100K thermistor temperature sensor
• the Acorn TEMP 6 uses a PT 100 RTD temperature sensor
All Acorn TEMP meters feature:
• Large LCD for clear and easy reading
• Readings in °C and °F (switchable)
• Minimum and maximum temperature display
• Minimum and maximum hold mode
• Low battery indicator
• Hold function, freezes measured reading
• User calibration, offset adjustment
• Built-in memory backup; calibration and other information remain
if battery is disconnected
• TEMP 5 thermistor sensor allows selection of most suitable
temperature curve
This instruction manual is organized for easy reference. For basic functions of this
meter, read sections 2 through 5. These sections include basic instructions that will
get you up and running quickly. The remaining sections of this manual (6 through
11) deal with error messages and troubleshooting. This part of the manual also
