SYMBOLS � Caution! Refer to the explanation in this Manual � Complies with European Directives Tested Comply With FCC Standards = Do not dispose of this clamp meter as unsorted municipal waste. �WARNING and PRECAUTIONS • To avoid electrical shock, do not use this instrument when working voltages at the measurement surface over 24V AC or DC. • To avoid damage or burns, do not make temperature measurement in microwave ovens. • Repeated sharp flexing can break the thermocouple leads.
Note This equipment THWD-10W has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
Unpacking and Inspection Your shipping carton should include: 1 Meter 4 AAA batteries 1 Software CD ROM (THWD-10W) 1 USB Wireless Antenna (THWD-10W) 1 K type thermocouple 1 Manual 1 Plain white box If any of the items are damaged or missing, return the complete package to the place of purchase for an exchange. INTRODUCTION The instrument hereafter referred to as “the Meter” is a battery powered meter that measures relative humidity and temperature.
OPERATING INSTRUCTIONS “ ” Power Switch The “ ” key turns the thermometer on or off. In the SET mode cannot be powered off. Exit SET mode to power off. APO function mode Press “ ” power key for more than 4 seconds to disable the auto-power function. The display will show “APO OFF”. “°C/°F” Selecting the Temperature Scale Readings are displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F).
the current readings: MAX: The highest measurement recorded. MIN: The lowest measurement recorded. MAX-MIN: The difference of the highest and the lowest measurement. AVG: The average values of the measurements. Press “MIN/MAX” key over two seconds to exit the function. In this mode, press “HOLD” key to stop recording, all values are frozen, press “HOLD” key again to restart recording. In this mode, the APO function and other keys are disabled, excluding “HOLD” and Backlight keys.
“SAVE” Button The save function stores the %RH, K-TYPE, NTC, Wet bulb, Dew point data in a nonvolatile memory. Press the “SAVE” key to save the current data, the word SAVE is displayed to indicate the data are saved. The build in memory can store up to 256 data. “READ”, “p”, “q” Button To recall the readings from memory, press “READ” key. To check the memorized data just to press “p” or “q” until the desired memorized data is displayed. To return the meter to normal operation, press “READ” key again.
