DIAL GAUGE
BN 53 70 84 for testing mating face dimension 1.85 mm socket according to IEC 61169-32
These instructions were written for qualified and experienced personnel. Please read them carefully before starting work. Any liability or
warranty for the results of improper or unsafe use is disclaimed!
Handling & Cleaning Instructions
Range of application:
The dial gauge measures:
- Pin depth dimension
“d”
for standard test connectors (yellow range)
(Grade 0)
- Pin depth dimension
“d”
for general purpose connectors (green range)
(Grade 1)

M31064
| Issue I / 06.08.2018 | Data subject to change without notice
Handling:
- Clean interface of dial gauge, reference gauge and connector
- Check zero setting of pointer with the reference gauge
This procedure must be executed prior to the test of every inspection lot:
- Insert reference gauge and tighten with a torque wrench. Torque: 90
±10
Ncm
- Pointer = 0
:
pointer adjustment is not necessary
- Pointer ≠ 0 : loosen protective cap, adjust pointer to zero position and tighten protective cap
- Remove reference gauge
- Insert connector and tighten with a torque wrench. Torque: 90
±10
Ncm
- Check measured value of pin depth according to the ranges of tolerance
Note:
The dial gauge and reference gauge are precision measurement devices.
Therefore handle with care and consider as fol lowing:
• The dial gauge and the connector interface must be neat and clean
• Hold the calibration device steady and turn the nut only
• Hold dial gauge and reference gauge at the knurled handle only
• Do use the included reference gauge only.
• Always use a torque wrench (Order no.: BN 15 41 41 R000) to achieve best
measurement accuracy and repeatability. Torque: 90
±10
Ncm.
• Measuring temperature: 23
±5
°C
• Protect against humidity
• Prevent soiling
• Avoid shocks
• Do not lubricate
• A calibration is recommended at regular intervals
The suggested initial interval for recalibration is 12 months. The actual need
for recalibration depends on the use and the maintenance of the gauge.
The recalibration interval should begin with the day of initial use.
Pin depth is the distance between outer conductor mating plane and inner conductor mating plane.Positive values stand for
protrusion of the inner conductor, negative values for recession.

Range of measurement is the limit for the measured value (resultant average of minimum three measurements) due to the
measurement uncertainty. This value is still within the specification. The measurement uncertainty is based on the handling
discribed in this instructions. Deviations cause higher measurement uncertainty.
