5. Preparation for Measurement 5-1 Installing Batteries WARNING ¡To avoid possible electric shock hazard, set the function selector switch to the OFF position and remove the test probe connector from the socket before opening the battery compartment cover. After battery replacement, do not use the instrument before securing the cover with the two screws. ¡Never mix old and new batteries. ¡Install batteries in correct polarity as shown inside the battery compartment. 1.
5-2 Mechanical Zero Adjustment With the function selector switch set to the OFF position and without pressing the test button, turn the zero adjuster with a screw driver so that the pointer lines up with the ∞ mark on an insulation resistance scale. 5-3 Connecting Test Leads Slide the sliding shutter over the terminals for precision earth resistance measurement to reveal the probe socket. Insert the test probe connector into the probe socket correctly as shown below.
5-4 Battery Voltage Check 1. Set the function selector switch to the BATT CHECK position. 2. Press the test button or the remote control switch. 3. If the meter pointer does not reach the "BATT GOOD" area, replace the batteries as shown in section 5-1 "Installing Batteries." CAUTION ¡Do not keep the test button pressed or locked down during battery check to avoid battery power drain. Batteries have exhausted. Replace the batteries. Proceed to measurement.
5-6 Scale Illumination Function To facilitate working in dimly lit situations, a function to illuminate the scale plate is provided. To operate this function, depress and release the light button. The light will be switched on for about 60 seconds before it goes off. 5-7 Attaching Neck Strap Attaching the provided neck strap permits the use of the instrument with strap hung around the neck. This allows two-hand operation, facilitating field work.
5-8 Fitting Case Lid Under Case 1.Open the case lid as shown. 2.Turn it 180 degrees. 3.Put the case under the housing case. 4.Hook it onto the housing case.
6. Measurement 6-1 AC Voltage Measurement (Mains Disconnection Check) An AC voltage range is provided for mains voltage measurement. If any voltage is present on the circuit under test in insulation resistance measurement, the display also reads the voltage before the test button is pressed. Note: ¡On any range, the instrument measures and displays AC voltage while the test button is not depressed.
1. Set the function selector switch to AC600V. Connect the earth probe (alligator clip on black lead) to earth of the circuit under test and the line probe (red) to the other side as shown below. If the circuit is not earthed, connect the earth probe to an appropriate conductor. 2. Do not press the test button or the remote control switch. Take the reading on the AC voltage scale. 3. Set the function selector switch to the OFF position. Note:注意：測定スイッチは Do not press the test button.
6-2 Insulation Resistance Measurement The insulation resistance function is used for insulation check on electric appliances, wiring systems, etc. The circuit under test must be disconnected from mains and de-energized before attempting to make measurement. Check the maximum voltage that may be applied to the circuit under test. Note: ¡In some cases, insulation resistance values are not stable, causing the reading to vary during measurement.
2. Check the maximum voltage that may be applied to the circuit under test. Set the function selector switch to an appropriate insulation resistance range. 3. Connect the earth probe (alligator clip on black lead) to the earth terminal of the circuit under test. If the circuit is not earthed, connect the earth probe to an appropriate conductor. 4. Connect the line probe to the circuit under test and press the test button or the remote control switch. 5.
6-3 Continuous Insulation Resistance Measurement A lock down feature is incorporated on the test button. Pressing and turning it clockwise lock the button in the continuous operation position. To release the lock, turn the test button counter clockwise. DANGER ¡Never touch the tips of the test probes or the circuit under test during insulation resistance measurement to avoid possible shock hazard.
6-5 Earth Resistance Measurement The earth resistance function is used to check that equipment is properly earthed to provide appropriate protection against shock hazard to the user or damage to the equipment. Select the precision or simplified mode, then select the desired measuring range. Use the optional test leads for precision measurement. DANGER ¡Never touch the tips of the test leads or the circuit under test during earth resistance measurement to avoid possible shock hazard.
Make sure to drive the auxiliary earth spikes in the moist part of the earth. Give enough water if the auxiliary earth spikes have to be stuck into dry, stony or sandy part of the earth so that it may become moist. If it is not possible to drive the auxiliary earth spikes into a hard surface, such as concrete ground, lay the earth spikes there, cover them with a cloth and put water (preferably salt water).
CAUTION ¡When earth voltage is more than 10V, accurate earth resistance measurement can not be made. Reduce the earth voltage, for example, by detaching the earth electrode from the equipment that it connects to or the disconnecting mains from the equipment. ¡When connecting the test leads, make sure that they are separated. If the test leads are twisted or in touch with each other, induction voltage or current may result to affect measurement accuracy.
When making earth resistance measurement using a wall outlet, which is on the secondary side of mains power supply, use a probe with a blade type prod, instead of an alligator clip, as earth probe. (See section 8 "Adapters for Earth Lead and Replacement") Locate earth of the outlet and insert the blade type prod into it. 2. Check earth voltage. Select the "earth voltage AC 60V " range and check whether the reading is 10V or less. When earth voltage is more than 10V, it may result in errors in the reading.
Note: ¡When mains power supply that includes a residual current circuit breaker is used for simplified measurement, the circuit breaker does not trip since test current is as low as about 2mA.
7. Test Prods for Line Probe and Replacement 1. Types of test prods Model 8072: Standard Test Prod Used in ordinary situations. This type of prod is fitted to the line probe at the time of shipment. Model 8017: Extension Prod Used in difficult-to-reach situations. Model 8016: Pickel Prod (Optional): Used to hook the line probe on a conductor. 2. How to Replace Prod To remove the test prod, turn the cap of the line probe counter clockwise.
8. Adapters for Earth Lead and Replacement 1. Types of earth lead adapters Model 7131: Safety Alligator Clip Used to connect to an earth terminal, including an earth terminal board. Model 7101: Probe with Blade Type Prod Used to connect to earth of a mains wall outlet. 2. How to exchange earth lead adapter Pull the adapter to remove it from the plug of the earth lead. Insert another type of adapter fully into the plug of the earth lead.
9. Optional Accessories Model 7100 Model 8016 Model 7095 Model 8032 Model 8200 Model 9091 Test Lead Set for Precision Earth Resistance Measurement (includes Test Leads, Carrying Case, Cord Reels, Auxiliary Earth Spikes) Pickel Prod Earth Resistance Test Leads Auxiliary Earth Spikes (Two pieces) Cord Reels Carrying Case for Cord Reels 9-1 How to Use Test Leads and Cord Reels Handling and storing earth test leads is always troublesome for the user.
10. Cleaning Meter Cover Do not try to remove dirt on the meter cover by rubbing hard with a dry cloth. This can remove anti-electrostatic agent applied to the surface of the meter cover. When the meter reading is affected by electrostatic build up on the meter cover, wipe the meter cover surface using a cloth dampened with off-the-shelf anti-static agent or detergent. To avoid possible deforming or discoloring, do not use solvents. To clean the body of the instrument, use cloth dampened with detergent.
11. Before Sending for Repair Use the following troubleshooting guide for hints on problems with instrument operation. Condition The meter does deflect in BATT CHECK. "Power-on" indication LED does not light up when the test button is pressed on insulation resistance ranges Possible Cause "Power-on" indication LED does not light up on AC voltage range. This is not a failure.
