GENERAL OPERATION
1. Press (or rotate for Model PSH/ESH) Peak Switch OFF.
2. Hand tighten (no tool!) selected attachment to the measuring shaft.
3. Rotate Tare Ring to read “0” to tare the weight of attachment and measuring shaft orientation.
4. Begin measuring.
Real Time Mode: the Peak Switch is OFF and the gauge displays force as it changes. During Real Time Mode,
you can hold a critical reading by turning the Peak Switch to the ON position.
Peak Mode: the Peak Switch is ON and the gauge will retain highest reading taken which will not change until a
higher value is measured. Turn the Peak Switch OFF to zero the gauge and turn it ON again to measure Peak
values.
MOUNTING
When mounting mechanical gauges to test stands, hold the gauge firmly and unscrew the 4 screws
in back, making sure the case does not separate. (FIG. 1)
AP-002 adapter plate mounts mechanical gauges to test stands. Align plate and gauge holes and
insert the 4 long screws supplied to attach gauge. Then utilize the 4 PEM nuts on the adapter plate
to mount to test stands with the mounting bolts supplied.
AP-001 adapter plate mounts low capacity gauges to most other brands of test stands. Use the 4
screws (supplied) to mount the gauge to the AP-001 adapter plate. Then utilize the 2 PEM nuts on
the AP-001 adapter plate to mount to other brands of test stand.
IMPORTANT
1. Do not exceed capacity of unit and avoid shock loading.
2. Failure to allow for sufficient overload capacity in the load, structure and mounting
elements, may result in property damage, serious injury, and death. For applications
involving suspension of equipment, additional safeguards are also a necessity.
3. Do not use the tension shaft to measure compression or the compression shaft to measure
tension.
4. Accuracy may be affected if unit is exposed to high humidity, dust or extreme shock.
5. Do not apply oil or chemical soap, which causes corrosion or dust adhesion.
6. Do not remove warranty seal or disassemble gauge. Disassembly voids warranty.
7. Recommended recalibration cycle is one year.
8. Specifications subject to change without notice.
