INNOVA 3306 - Hands-Free DMM (10 MegOhm) Manual

SAFETY PRECAUTIONS/WARNINGS

• This Digital Multimeter is intended for INDOOR USE ONLY.
• Pay close attention to stamped on the front and rear of the meter's case. These warnings, as well as all warnings and precautions used through out this manual, must be followed to avoid electric shock and/or personal injury.
• The RESPONSIBLE PARTY shall be made aware that, if the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
  To prevent electrical shock and/or damage to the tester or the equipment under test, observe the following safety precautions:
• DO NOT apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground.
• Use caution when working above 30V AC rms, 42 V peak, or 60 V DC. Such voltages pose a shock hazard.
• To avoid false readings that could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicator displays.
• Use ONLY those test leads or probes provided with the meter. DO NOT use thirdparty test leads or probes.
• Always inspect the multimeter, test leads and any other accessories for damage prior to every use. If any damage is found, do not use tester until repairs are done.
• Always consider electrical and electronic equipment to be ener-gized (live). Never assume any equipment is de-energized.
• Never ground yourself when taking electrical measurements. Isolate yourself from ground by using dry rubber insulating mats to cover all exposed/grounded metal. Stand on rubber mats and wear dry clothing.

GENERAL SPECIFICATIONS AND FEATURES

ELECTRICAL SPECIFICATIONS

Accuracy of specifications in the following tables are based on an operating temperature of 64°F to 82°F (18°C to 28°C) and a relative humidity of less than 75%.
Maximum voltage from V ma socket to COM socket is 500V AC/DC; from COM socket to ground is 300V AC/DC.

TESTING PROCEDURES

1. AC/DC VOLTAGE MEASUREMENT
   
   To avoid possible electric shock, instrument damage and/or equipment damage, DO NOT attempt to measure voltages ABOVE 500V AC/DC or take measurements if the voltage is unknown. 500V AC/DC between the COM and V jacks is the maximum voltage that this instrument is designed to measure. The "COM" terminal potential should not exceed 300V AC/DC measured to ground.

1. Plug the BLACK test lead into "COM" jack of the multimeter; plug the RED test lead into the "V" jack.
2. Set the meter's Function/Range Selector Switch to the appropriate ACV or DCV position as desired.
3. Place the RED test lead onto the positive (+) side of the item being tested and the BLACK test lead onto the negative (-) (across the source/load) side of the item. BE CAREFUL not to touch any energized conductors with any part of your body.
4. Read the results on the display.

1. Plug the RED test lead into the "Ω Ω " jack of the multimeter; plug the BLACK test lead into the "COM" jack.
2. Set the meter's Function/Range Selector Switch to the OHM "Ω Ω " range function.
3. Place the RED test lead onto one side of the item being tested and the BLACK test lead onto the other side of the item. (Polarity does not matter when checking resistance).
4. Read the results on the display.

1. Plug the RED test lead into the jack of the multimeter; plug the BLACK test lead into the "COM" jack.
2. Set the meter's Function/Range Selector Switch to the position.
3. Place the RED test lead onto one side of the diode being tested and the BLACK test lead onto the other side.
4. Read the results on the display.
5. Reverse the test leads and again read the results on the display. Compare the two readings. One reading should indicate a voltage drop value; the other reading should indicate an overrange (1) condition.

1. Plug the RED test lead into the "mA" or the "DC10A" jack of the multimeter, as applicable; plug the BLACK test lead to the "COM" jack.
2. Set the meter's Function/Range Selector Switch to the appropriate Amps range position as desired.
   • To measure from 0 to 200mA, set the Selector Switch to the desired "DCmA" position.
   • To measure from 200mA to 10 Amps DC, set the Selector Switch to the "DC10A" position.
3. Disconnect the battery, or shut off the power to the circuit being tested.
4. Disconnect one end of the wire or device, from the circuit where current will be measured.
5. Place the RED test lead on the disconnected wire and place the BLACK test lead at the location from which the wire was disconnected (series connection).
6. Reconnect the battery, or apply power to the circuit being tested.
7. Read the results on the display.

After the test is completed, shut the power off to the circuit before removing the test leads and before reconnecting any disconnected wires or devices.

5. BATTERY TEST

1. Plug the RED test lead into the "BAT." jack of the multimeter; plug the BLACK test lead into the "COM" jack.
2. Determine the voltage rating of the battery to be tested.
3. Set the meter's Function/Range Selector Switch to the desired "Battery Test" range.
4. Place the RED test lead on the positive post of the battery under test; place the BLACK lead on the negative post.
5. Read the results on the display.

BATTERY AND FUSE REPLACEMENT

When replacing the battery or the fuse, remove only the rear panel. Do not remove or disassemble the circuit board or the front panel, these items are not serviceable and if disassembled there is the possibility of loose metal parts shorting the circuit board and causing an electrocution danger to the user.

1. Turn the Digital Multimeter "OFF" and remove the test leads.
2. Remove the two screws on the back of the meter and separate the case.
3. Replace the fuse or battery as necessary:
   • For battery replacement: Remove the battery from the battery compartment and replace only with one 9-volt alkaline battery.
   • For fuse replacement: Remove the fuse from the fuse holder and replace with a 0.315A/250V - UL Listed Bussmann, GMA Type (Radio Shack GMA/270 series; #270-1046 ) fuse.
     NOTE: Use a 0.315A/250V, 5x20mm type fuse ONLY - Bussmann, GMA Type (Radio Shack #270-1046 or similar). Using an incorrect fuse may result in serious injury and/or damage to the unit.
4. Reassemble the case and secure with the two screws.
