GENERAL DESCRIPTION & FEATURES Thank you for your purchase of Delmhorst Instrument Co’s newly designed TechCheck handheld moisture meter. The TechCheck offers the latest in features and functionality and is intuitive and easy to operate. We recommend that you read the following pages in detail to take full advantage of all that the TechCheck has to offer.
OPERATING INSTRUCTIONS -User GuideThis guide provides step-by-step instructions on powering up, using and powering down the meter. INSTALLING THE BATTERY: The battery compartment is located on the underside of the case, at the bottom of the handle. 1. Open the battery compartment by sliding the lid back while pressing on the release indent. 2. Ensure correct polarity, and push the battery in flush with the bottom board until the connectors snap together on both sides. 3.
TO POWER THE METER ON: To turn the meter on, press and hold the center HOLD (SELECT) KEY for approx. 2 seconds. The meter will start in PIN mode. METER USE TO TAKE PIN READINGS: 1. Press the PIN (ï) button to enter the pin mode. 2. The meter will display the PIN mode screen, as shown below: 3. Push the contact pins into material to be tested. Any Delmhorst electrode may also be used in PIN mode by simply attaching it to the connector next to the contact pins. 4.
falls below 30 percent. Otherwise, these high readings provide relative comparisons, indicating that the material is taking on or losing moisture. 5. To hold a reading on-screen, press the HOLD (SELECT) KEY. Press the HOLD (SELECT) KEY again to return to measuring mode. NOTE: The TechCheck is calibrated to give %MC readings on Douglas Fir. If you are taking readings on other species of wood, refer to the species correction chart found on pages 1415. TO SET THE ALARM IN PIN MODE: 1.
4. To hold a reading on-screen, press the HOLD (SELECT) KEY. Press the HOLD (SELECT) KEY again to return to measuring mode. NOTE: The SCAN mode will give relative readings only, not %MC. The numbers displayed represent the relative dryness or wetness of the material on a scale of 0 to 300.
TAKING A READING – PRACTICAL APPLICATIONS The following application notes are intended for use with the meter in PIN MODE except where otherwise indicated. TESTING WOOD: The contact pins provided are best for materials up to 6/4. On materials over 6/4 or for hardwoods over 4/4 we recommend using a remote probe such as the 26-ES ram-type electrode. Mount the 26-ES directly to the external connector.
meter’s PIN mode will give relative readings only, not %MC. The numbers displayed represent the relative dryness or wetness of the material on a scale of 5 to 60. In order to accurately interpret your readings, first establish a baseline reading by taking a reading in an area you know to be unaffected, then take a reading in the affected area and compare the two readings. TESTING CONCRETE SLABS FOR FLOORING APPLICATIONS Moisture meters are an effective tool to check moisture in concrete.
If the meter still indicates a “dry” condition, the floor is ready for covering. Tests should be made at several points, especially when the slab is thick (4” or more) and air circulation is poor. Make tests only in newly drilled holes. When evaluating a slab for readiness, always consider its age, thickness, whether the slab is on grade or suspended, whether a vapor barrier is present and the drainage condition of the ground.
CARE OF YOUR METER Ø Store your meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is not in use. If the meter has been left in a hot or cold environment overnight or for an extended period, the calibration of the pinless mode may be adversely affected. Under these conditions, allow the meter to acclimate to the temperature conditions in which it will be used for minimum 1-2 hours, or as long as possible. Ø Change contact pins as needed.
SERVICE FOR YOUR METER Ø Before sending in your meter we recommend you give one of our trained technicians a call. Many times troubleshooting can be taken care of over the phone.
