TightSight™ Display Notes:
Only AC/DC amps units of measure are displayed in the TightSight™ display since primary use is
for viewing current measurements in tight locations. The display will show numerical values only
for other functions. The main display is to be used to view units of measure for all other
functions.

High Voltage Warning (HI-V):
The meter beeps and lights an LED when >30V AC on ACVoltage function or >30V DC on DC
voltage function is present. This enhanced safety feature alerts the user when dangerous voltage is
present.
Notes: This feature does not work through the clamp head as the clamp is intended to only
measure current. Audible indication can be turned off by pressing and holding the MAX/MIN
button while turning the function switch from OFF to the desired range position.

PERFORMANCE VERIFICATIONS
Perform the following analysis; if the meter conforms to the limits listed in Table 1 through 7 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 use 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 (see Battery Replacement page 11)
before beginning the performance test.
3. Input the values listed in Table 1 through 7.

CALIBRATION
Calibration Preparation
1. Turn on the calibrator, allow calibrator to warm up. Perform calibration at
23±2°C (73.4°F ±3.5°F) at relative humidity of < 70%. Temperature stabilization should be
reached after 30 minutes.
2. Disconnect the test leads and turn the range switch to “OFF”.
3. It is recommended that a new battery be installed before you begin calibration.
To replace the battery (see Battery Replacement page 9).
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.
Auto Calibration:
Set the short circuit 2-pin connector, mounted on PC board, from J2 to J1 position. Replace the case
bottom of the meter. It is allowed to do calibration for any one of the following functions that is
inaccurate. There is no need to do calibration for all functions.
V AC Calibration
1. Set Function Switch from OFF to ACV position.
2. Short the V and COM inputs on the meter. After a reading in the LCD is settled (about 5 seconds),
press MAX/MIN button until unit display reads 000.0V ± 1 digit. Zero adjustment is complete.
3. Connect the calibrator to the V and COM inputs on the meter.
4. Output AC 50V/50Hz. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN
button until unit display reads 48V ~ 50V. Adjustment is complete.
5. Output AC 500V/50Hz. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN
button until unit display reads 500.0V ± 2 digits. Adjustment is complete.
V DC Calibration
1. Set the function switch to DCV range. After a reading in the LCD is settled (about 5 seconds), press
MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero adjustment is complete.
2. Connect the calibrator to the V and COM inputs on the meter.
3. Output DC +500V. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button
until unit display reads 500.0V ± 2 digits. Adjustment is complete.
Continuity Calibration
1. Set the function switch to Continuity range. Short the V and COM inputs on the meter. After a
reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display reads
000.0 ± 1 digit. Zero adjustment is complete.
2. Connect the calibrator to the V and COM inputs on the meter.
3. Output 800.0 . After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button
until unit display reads 800.0 ± 2 digits. Adjustment is complete.

Resistance Calibration
1. Set the function switch to range. Short the V and COM inputs on the meter. After a reading in
the LCD is settled (about 5 seconds), press MAX/MIN button until unit display reads 000.0 ± 1
digit. Zero adjustment is complete.
2. Connect the calibrator to the V and COM inputs on the meter.
3. Output 800.0 . After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button
until unit display reads 800.0 ± 2 digits. Adjustment is complete.
4. Output 8K . After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until
unit display reads 8000 ± 2 digits. Adjustment is complete.
Capacitance Calibration
is settled (about 5 seconds), press MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero
adjustment is complete.
2. Plug a 390uF standard capacitor to V and COM inputs. Press MAX/MIN button until unit display
reads 390.0 ± 5 digits. Adjustment is complete.
A DC Calibration (61-765 only)
1. Set the function switch to DCA range. After a reading in the LCD is settled (about 5 seconds), press
MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero adjustment is complete.
2. Set output of the DC calibrator for 7.8A DC and connect it to Coil = 50N = 390.0A DC.
3. Clamp the jaws to the coil = 50N.
4. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display
reads 390.0A ± 2 digits. Adjustment is complete.
