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 7.5 V
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 for the Standard 61-362

CALIBRATION
Calibration Preparation
Required Equipment
The class of calibrator or equipment should have an accuracy that exceeds, by an expectable ratio the
accuracy of this instrument.
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 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 7.5 V 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.
61-362 Calibration Procedure.
Calibration
1. Set the Function/Range Switch to the “3.200V DC” position.
2. Set the output of the DC calibrator for 3.000V and connect it to the “V-Ohm” and “COM”
input terminals.
3. Adjust VR1 (VR 200 ohm) until the display reads 3.000V +/- 1 digit.
Note : This is the only adjustments required for the 61-362. Calibration is complete.
Battery Replacement (refer to Figure 2)
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. Remove battery from compartment noting the “+” and “- “ position of the Battery terminals.
4. Remove the Battery plastic sleeve and place it on the new battery
(Damage can occur to circuit if Plastic sleeve is not replace with new Battery)
5. Install new 9V battery into compartment and assure proper polarity of battery.
(An alkaline type NEDA #1604 is recommended.)
6. Install bottom case cover and secure with screws.

Replacing Fuse (refer to Figure 3)
1. Disconnect the test leads and turn the range switch to “OFF”.
2. Remove the three screws holding the bottom case cover
3 Us a digital multimeter in low resistance {ohms} mode to check the two fuses
mA input, 0.5A / 250V fast acting fuse.
Amp input, 10A / 600V fast acting fuse
4. Remove the defective fuse with the recommended fuse
mA with : 0.5A/250V fast acting fuse Type LA-3895 is recommended.
Amp with: 10A/600V fast acting fuse, Type LA-3897 is recommended
5. Install bottom cover and secure with screws.
