PERFORMANCE VERIFICAITONS
Perform the following analysis, if the meter conforms to the limits listed in Table 1 the meter is functioning
correctly. If the meter does not conform to any of the listed limits the calibration procedure must be
performed.
Performance Verification Preparation
1. Turn on the Calibrator, allow calibrator to warm up. Temperature Stabilization
should be reached after 30 minutes.
2. Remove battery cover and using a calibrated meter to ensure the battery measures a minimum of 7.5V
DC. If the battery measures under 7.5V DC, replace the battery before beginning the performance test.
3. Input the values listed in Table 1

CALIBRATION
Calibration Preparation
1. Turn on the Calibrator, allow calibrator to warm up. Temperature Stabilization
should be reached after 30 minutes.
2. Disconnect the test leads and turn the range switch to “OFF”.
3. Remove the screws holding the battery cover and one at the jaw.
4. Remove the case bottom using care not to damage the battery connector and leads
to the continuity beeper. (Beeper is attached to the bottom case cover.)
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.
The class of calibrator or equipment should have an accuracy that exceeds, by an expectable ratio the
accuracy of this instrument.
Volts DC Calibration
1. Set the function / range to 600V DC
2. Connect the calibrator to the Vand COM inputs on the meter.
3. Output 100V DC.
Adjust R43 until unit display reads 100V
De-energize source and remove test leads
DCA Zero Calibration:
1. Remove the Jumper
2. Set the function / range to the 200A DC
3. Without any signal applied (keeping Jaw away from other devices)
adjust R54 for a display reading of 0.0 ±1 digit
4. Replace the Jumper, then press the “ZERO” button
adjust R506 for a display reading of 0.0 ±1 digit
DCA Balance Calibration
1. Set the function / range to the 200A DC.
2. Clamp the unit to a 100A DC source.
2.a Move the jaw to the top of the clamp {see figure 1a} and note reading
2.b Move the jaw to the bottom of the clamp {see figure 1b} and note reading
2.c Repeating steps 2a and 2b, Adjust R581 until the difference of measured readings
in step 2a and 2b is within 5 digits
DCA Calibration
1 Set the function / range to 200A DC
2. Clamp the unit to a 100A DC Source
Note: Use care to keep the Jaw (CT) of the unit properly centered to the Source
3. Adjust R62 until the display reads 100.0 ±2 digit
Calibration of the 61-724 is complete.
Remove all leads from the calibrator and equipment.
Return unit to proper operating condition.

Placement of source for DC Balance Calibration
Battery Replacement (refer to Figure 2)
1. Disconnect the test leads from any circuit under test and turn off meter.
2. Use a Philips head screwdriver to remove the two screws on battery cover
3. Remove battery from compartment and unsnap the battery connector.
4. Install new 9V battery (NEDA #1604). An alkaline type is recommended.
5. Install new battery into compartment using care not to pinch or bind battery leads
6. Reinstall battery cover.
