TECHNICAL BULLETIN TB-4009 Low Resistance Tester Made in America Operation and Maintenance Battery Replacement Batteries are easily replaced by removing the rear cover (where the wire lead exits). Remove the 2 screws and simply slide the circuit board assembly out. Remove the old batteries and replace them with 2 alkaline AA batteries, noting the proper polarity. Rechargeable NiCad batteries can also be used, but they must be recharged externally. Reassemble the unit, taking care that the front probe is oriented properly to pass through the square hole in the front panel. Calibration Rough field calibration may be accomplished using the Menda 35106 Calibration Unit. Applying the Low Resistance Tester to the Calibration Units Pass and Fail test points allows for easy calibration. In the event that the unit requires adjustment, this can be accomplished by removing the rear cover as done for battery replacement and sliding the circuit board out. Place the circuit board assembly on an insulated surface on the bench and Figure 1. Item 35105, Menda Low Resistance Tester install fresh batteries. Locate the trimpot adjustment near the LED and turn it gently counter-clockwise to the stop. Apply the Pass resistance value, while depressing the board-mounted Features switch. Slowly turn the trimpot clockwise just to the point where This Menda Low Resistance Tester is designed to test the signals come on. If this is done carefully, the setting can be resistance in the area of 0.1 ohms. It indicates a resistance of adjusted within 1% of the 0.1 ohm reference. Confirm that the 0.1 ohms, or less, by an audible signal as well as the Fail resistance provides no signal. Reassemble the unit, taking illumination of a blue LED. Resistances above this range care that the front probe is oriented properly to pass through simply will cause no signal. The Tester operates on 2 standard the square hole in the front panel. AA alkaline batteries. When the combined voltage of the 2 X AA batteries declines to about 1.6 volts, the Tester will give a Limited Warranty pulsing audio and visual indication when the front probe is depressed indicating low batteries needing replacement.
