Basic Maintenance
Warning
To avoid shock, remove the test leads and any input signals before opening
the case or replacing the battery or fuses.
Opening Meter Case
Caution
To avoid unintentional short circuit, always place the uncovered Meter
assembly on a protective surface. When the case of the Meter is open,
circuit connections are exposed.
To open the Meter case, refer to Figure 1.1 and do the following:
1. Disconnect test leads from any live source, turn the rotary switch to OFF, and remove
the test leads from the front terminals.
2. Remove the battery door by using a flat-blade screwdriver to turn the battery door
screws 1/4 turn counterclockwise.
3. The case bottom is secured to the case top by three screws and two internal snaps
(at the LCD end). Using a Phillips-head screwdriver, remove the three screws.
4. Hold the Meter display side up.
5. Lifting up on the input terminal end, disengage the case top from the gasket.
6. Gently unsnap the case top at the display end.
Note
The gasket between the two case halves is sealed to, and must remain with, the case bottom. The case top
lifts away from the gasket easily. Do not damage the gasket or attempt to separate the case bottom from the
gasket.
Figure 1.1
Form number TM61494-5 Rev 2 February 2002
Page 11
Figure 1.2
Replacing the Battery
The Meter is powered by a single 9V battery (NEDA 1604, 6F22, or 006P).
To replace the battery, refer to Figure 1.2 and do the following:
1. Turn the rotary switch to OFF and remove the test leads from the terminals.
2. Remove the battery door by using a flat-blade screwdriver to the turn the battery
door screws 1/4-turn counterclockwise.
3. Remove the battery and replace it with a new one. Dress the battery leads so that
they will not be pinched between the battery door and case bottom.
4. Replace the battery door and secure the door by turning the screws 1/4-turn clockwise.
Testing Fuses (FS1 and FS2)
To test the internal fuses of the Meter, refer to Figure 1 and do the following:
1. Turn the rotary selector switch to the mA position for 1A fuse test FS2 or
A position for 15A fuse test FS1.
2. To test FS2, plug a test lead into mA input terminal, and turn the rotary selector to
the mA position.
2.1 Fuse is OK if the Display shows normal functional graphics.
2.2 Fuse is defective if “Prob” is displayed and the built-in beeper alarm is on.
3. To test FS1, plug a test lead into A input terminal, and turn the rotary selector to
the A position.
3.1 Fuse is OK if the Display shows normal functional graphics.
3.2 Fuse is Defective if “Prob” is displayed and the built-in beeper alarm is on.
Form number TM61494-5 Rev 2 February 2002
Page 12
Replacing Fuses
Warning
To avoid electrical shock, remove the test leads and any input signals before
replacing the battery or fuses. To prevent damage or injury, INSTALL ONLY
quick acting fuses with the following Amp/Volt current interrupt rating:
FS1 Fuse: 15A, 600V, FAST. Minimum interrupt rating 100,000A
FS2 Fuse: 1A, 600V, FAST. Minimum interrupt rating 10,000A
1. Open the case as described in “Open Meter Case” section, steps 1 – 6
2. Gently lift the case top to separate the two halves of the case.
3. Remove the fuse by gently prying one end loose, then sliding the fuse out of its
bracket.
4. Replace the fuse only with one specified above.
5. Verify that the rotary switch and the circuit board switch are in the OFF position.
6. Place the case top on the case bottom, ensuring that the gasket is properly seated and
the case halves snap together (See Figure 1).
7. Reinsert the three case bottom screws and the battery door.
Cleaning
Warning
To avoid electrical shock or damage to the Meter, never allow water inside
the case. To avoid damaging the Meter’s housing, never apply solvents to
the Meter.
Input Terminals
Water, dirt, or other contamination in the A or mA input terminals may
activate the Input Alert beeper even though test leads are not inserted.
Such contamination might be dislodged by turning the Meter over and,
with all test leads removed, gently tapping on the case.
To clean the input terminals more effectively, do the following:
1. Turn the Meter off and remove all test leads from the terminals.
2. Use a clean swab in each of the four terminals to dislodge and clean out the
contamination.
3. Moisten a new swab with a cleaning and oiling agent. Work this swab around in each
of the four terminals. The oiling agent insulates the terminals from moisture-related
shorting and ensures against false Input Alerts.
Performance Tests
The following performance tests verify the complete operability of the Meter and checks the accuracy of
each Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an operating
temperature of 18°C to 28°C and at a maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case; no adjustments are necessary. Merely
make the required connections, apply the designated inputs, and determine if the reading on the Meter display
falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Form number TM61494-5 Rev 2 February 2002
Page 13
A Basic Operability Test
To check the basic operability, do the following:
1. Turn the rotary switch to A and plug a test lead into A input terminal, display is of
functional graphics if the fuse is good.
2. Then test the mA input fuse (1A) by inserting a test lead into mA input terminal and
turn the rotary switch to mA. (A input must be open).
The display is of normal functional graphics if the fuse is good.
If the Meter fails to operate properly:
• Check the battery and fuses and replace as needed.
• Verify that you are operating the Meter correctly by reviewing the operating instructions
found in the Users Manual.
To complete a comprehensive performance test and verify the accuracy of each Meter function and
operation, perform the remainder of the tests under “Performance Tests”.
Testing the Display
Press Bar key and turn the meter on from the OFF position to hold the Meter in Display Test Mode.
Compare the display with the appropriate example in Figure 2. Turn off the meter to escape the test mode.
LCD Display of the 61-490 Series
Testing the Voltage Function
To verify accuracy in the AC and DC voltage ranges, do the following:
1. Connect the Calibrator to the VΩ and COM inputs on the Meter.
2. Set the Calibrator for the voltage and frequency from step 1 to 19 in Table 1.
3. Compare the reading on the Meter display with the display reading shown in Table 1.
4. If the display reading falls outside of the range shown in Table 1, the Meter does not
meet specification.

Calibration
Calibration of the meter is recommended once a year to ensure performance according to the published
specifications.
Calibration is performed with the use of CalWin 109VPTCM Software as illustrated above.
(This software can be obtained by contacting Customer Service at IDEAL INDUSTRIES, INC.)
Do not perform this step if software is already loaded.
The software consists of three files titled Setup.exe, Data001, and Data002. After you execute the
setup.exe program in the Window (95 or 98) environment, you will have 109CalVPTCM100 option in the
PROGRAM set.
Execute CalWin109VPTCM choice and you should get the screen shown in Figure 3.
Description of CalWin109VPTCM window:
1. Main Function Indicator: Displays the function of the Meter.
2. Main Display: Displays the main reading of the Meter.
3. Connection Indicator: “Connection” shows that the meter is connected to your
computer and the meter and computer are communicating
“Disconnection” shows that the meter and computer are not
connected or are not communicating.
Form number TM61494-5 Rev 2 February 2002
4. Communication Port: Selects port available to connect to meter.
Selectable ports are COM 1 or COM 2.
5. Error Indication: Displays error message when an error of calibration occurred.
When an error occurs, press the blinking (RESET) key to display mode.
6. Calibration Function Indicator: Indicates the calibration function selected.
It disappears if the calibration function has not been selected or the calibration
is completed.
7. Calibration Function Selector: Select the calibration function desired.
Note Before the Calibration Function is selected, the function selected
on the Meter has to be confirmed, to prevent Mis-function error from occurring.
Calibrating the ACV Frequency Response
To calibrate the Meter, perform the following procedure:
Turn the rotary switch of the Meter to V
Connect the Calibrator to the VΩ and COM inputs on the Meter.
Output 100V/10KHz from the Calibrator.
