Disconnect the test leads and turn the range switch to OFF. 3. Remove the screw holding the bottom case cover, just above the battery cover. 4 The case bottom is secured to the case top by two internal snaps. (at the LCD end). lift up on the battery end until the case un-snaps. 5 Using a calibrated meter ensure the battery measures a minimum of 7.5V dc. If the battery measures under 7.5V DC, replace the battery. Calibration Procedure It is recommended that all IDEAL meters undergo the following calibration procedure on an annual basis. Volts DC Calibration 1. Set the Function/Range Switch to the 200mV DC position. 2. Set the output of the DC calibrator for 190.0mV and connect it to the V-Ohm and COM input terminals. 3. Adjust VR1 (VR 200 ohm) until the display reads 190.0mV +/- 1 digit. 4. Set the Function/Range switch to the 200mV AC position. 5. Set the output of the AC calibrator for 190.0mV/50Hz and connect it to the V-Ohm and COM input terminals. 6. Adjust VR2 (VR 200 ohm) until the display reads 190.0mV +/- 1 digit. Note : This is the only adjustment required for the 61-361. Calibration is complete. Battery Replacement (refer to Figure 1) 1. Disconnect the test leads from any circuit under test and turn off meter. 2.Remove the three screws for the back case cover. 3.

WARNING! 1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: - Voltage is not to exceed 600V AC or DC. - Resistance, Capacitance, Logic, and Continuity functions are not to be performed on circuits capable of delivering greater than 500V AC or DC. - Current measurements are not to be performed on circuits capable of delivering greater than 600V AC on insulated conductors, 250V AC on uninsulated conductors. 2. To avoid electrical shock hazards and/or damage to the meter: - Do not exceed the voltage ratings for the meter. Use caution when measuring voltage. - Do not use during electrical storms. AC power sources with inductive loads or electrical storms may result in high voltage. High energy transients can damage meter and present a dangerous shock hazard. - Turn off the power to the circuit or device being measured before taking resistance and capacitance measurements. Fully discharge all capacitors before measuring. 3. Ensure meter is in proper working order before using. Visually inspect meter for damage. Performing a continuity check can verify proper operation. If the meter reading goes from overload to zero, this typically means the meter is in proper working order. 4. Visually inspect leads for damage before using. Replace if insulation is damaged or leads appear suspect. 5. Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any other approved insulating material. Keep your fingers behind the finger guards on the probes. Work with others. 6. Before beginning all unknown measurements, set meter to the highest range possible.

WARNING! (cont.) 7. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. 8. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers,and solenoids.

5. Measure resistance. If necessary, perform the required multiplication to acquire the actual resistance. 5.1 Range Guide for Ohms (): 200 = Meter indicates actual resistance 2k = Multiply meter display reading by 1,000 to acquire actual resistance. 20k = Multiply meter display reading by 1,000 to acquire actual resistance. 200k = Multiply meter display reading by 1,000 to acquire actual resistance. 2M = Multiply meter display reading by 1,000,000 to acquire actual resistance 200M = Multiply meter display reading by 1,000,000 to acquire actual resistance. 6. The meter displays total resistance through all possible paths between the probe-tips. These multiple paths may result in measurements that do not correspond to the ohm value indicated by the resistor color code. Determining Resistor Values:
Resistor Color Code Table 1st Color Digit Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Gray 8 White 9 Gold Silver No Color Example: 2nd Tolerance Digit Multiplier (Percentage) 3 1,10,100,1,000,10,000,100,000,1,000,000,000 +/- 5% +/- 10% +/- 20%
To determine the value of a resistor, use the color bands on the resistor and the table on the following page.
1st color band is blue so the first digit is a 6 2nd color band is red so the second digit is a 2 3rd color band is yellow so multiply 62 x 10,000 4th color band is gold so the tolerance is 5% Your Resistor value is 620,000 Ohms (620k) with a tolerance of 5%.

All other repairs must be performed by a factory service center or other qualified instrument service personnel. Cleaning Case and window Periodically wipe the case with a damp cloth and detergent, allow to dry completely before using; do not use abrasives or solvents. Battery Replacement When the multimeter displays the replaced to maintain proper operation. the battery must be

Red Black Optional Clamp Adaptor To Use Accessories: Clamp adapters allow multimeters the versatility to measure large amounts of current safely through a clamphead. IDEAL clamp adapters convert amps measured into mV signals that the multimeter can display. Since the clamp adapters convert the amps measurement into mVAC, the clamp adapter leads must be inserted into the volts and com inputs and the meter must be set to the mVAC range. The conversion ratio is one-to-one (1Amp=1mV). So, when the meter displays 50.0 mV, the clamp adapter is measuring 50.0 Amps. For 300 AAC Current Clamp (61-450) with model 61-363: 1. Plug test leads into the meter inputs as indicated in the diagram above. 2. Remove the probe tips from the end of the leads. 3. Attach the leads to the current clamp (polarity will not affect reading). 4. a. Select 200 mVAC range for measuring less than 200 Amps. b. Select 2000 mVAC range for measuring more than 200 Amps. 5. Snap the jaw of the current clamp around one of the current carrying conductors. 6. Take the reading. Page 17

WARNING To prevent electrical shock hazard, turn off the multimeter and disconnect test leads before removing the back cover. 1. Disconnect the test leads and turn the meter off. Remove the test leads from the front terminals. 2. Position the meter face down. Remove the screws from the case bottom. 3. Lift the end of the case back until it gently unsnaps. 4. Lift the battery from the case back. 5. Replace battery. 6. Replace the case top. Reinstall screws. Fuse Replacement 1. Disconnect the test leads and turn the meter off. Remove the test leads from the front terminals. 2. Position the meter face down. Remove the screws from the case back. 3. Lift the end of the case back until it gently unsnaps. 4. Remove the fuse by gently prying one end of the fuse loose and sliding the fuse out of the bracket. 5. Verify continuity across the fuse. 6. If the fuse is good, return to tester. 7. If the fuse is blown, install a new fuse of the same size and rating. 8. Replace the case top. Reinstall screws. Troubleshooting The meter has been designed to be accurate, reliable and easy-touse. However, it is possible that you may experience difficulties during operation. If there appears to be any kind of problem during use of the multimeter, please perform the following steps to help determine the source: 1. Review and comply with the operating instructions section of this instruction manual. 2. Test the battery, replace as necessary. 3. Test the fuses, replace as necessary. 4. Check to see that the Function/Range Switch is in the correct position for the type of parameter and range of values being measured, and that the measurement value is within the capability of the multimeter. 5. Inspect the test leads for breaks or cracks, and ensure that the test leads are inserted fully into the input connectors. 6. If problem persists, meter should be inspected by a qualified service person. Page 19
