Troubleshooting! WARNINGTo avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitorbefore servicing, unless testing requires power.©2010 ACP, Inc. 16400009 23Operating Instructions for the HoladayHI1501, HI1510, and HI1710Purpose of these monitors is to check radiationleakage around microwave oven door or other placeswhere radiation could possibly occur.Instrument measures radiation leakage in milliwattsper square centimeters (mW/cm2). Probe should beused with the 2" (5 cm) cone spacer. Water load of275 cc. (approximately 1 1/3 cup), is to be placed inthe oven and used as a load during leakage tests.Operate the instrument on its internal 9 Volt batterypower supply. “Range” switch is used on low and highwhile using test probe. On an oven with an unknownleakage, use high scale then switch to low scale andtest for low leakage. “Bat Test” switch is used tocheck the battery and probe on the HoladayInstruments. If either is faulty, meter needle will notread above “Test Minimum” or battery mark on meter.Holaday Instrument has a probe test switch position.Meter needle must indicate in the “OK probe test”portion of the scale when in this position. Zero controlis used to zero the needle. “ON-OFF” switch providesa means of turning the operating voltage on or off.“Range Multiplier” switch provides a means ofselection either 0-2 or 0-10 and 0-100 on the HoladayInstruments sensitivity ranges.Test probe must be held by the grip portion of thehandle, otherwise a false reading may result ifoperators hand is between the handle and probe.If oven is likely to have a large amount of leakage,approach oven slowly with the probe, while observingmeter. This is achieved by holding the probe two orthree feet from oven surface or gap between door andoven body while observing meter. When high leakageis expected, do not move probe horizontally along theoven surface. This could cause possible probeburn-out. Greatest leakage is generally found at thecorners. After maximum leakage is established to bewithin the meter scale range, then probe may bemoved horizontally around the door surface.Hold probe perpendicular to cabinet door. Place coneof probe on the door and/or cabinet door seam andmove along the seam. If leakage of the oven isunknown, move probe slowly. Proceed with care inorder not to exceed a full scale reading of meter.When testing near a corner or access area of door,keep probe perpendicular to the areas making sureprobe end at the base of the cone does not get closerthan 2” (5cm) to any metal. If it does, an erroneousreading may result.Always use the 2” (5cm) spacer with probe. Also,always proceed carefully in areas of high leakage orprobe can be accidentally burned-out. Rotatingantenna causes high peaks of energy. Although meterhas averaging capabilities, probe will reactinstantaneously to peak power changes which willcause burn-out.
