JS MINI MANUAL
PLEASE READ COMPLETE INSTRUCTIONS BEFORE USE
Thank you for purchasing The Jennings MINI. With normal care and proper treatment it will provide years of reliable service. Please
read all operating instructions carefully. You can contact us at

.
KEEP THE FOLLOWING POINTS IN MIND:
* If the display becomes locked on Out2 please recalibrate the scale.
* Avoid lengthy exposure to extreme heat or cold, your scale works best when operated at normal room temperature.
Always
allow the unit to acclimate to a normal room temperature for at least one hour before use.
* Allow sufficient warm up time. Turn the scale On and wait several seconds to give the internal components a chance to stabilize
before weighing.
* The cleaner the environment the better. Dust, dirt, moisture, vibration, air currents and proximity to other electronic equipment can all
cause an adverse effect on the reliability and accuracy of your scale.
* Handle with care. Gently apply all items to be weighed onto tray top. Although this scale is designed to be quite durable, try to avoid
rough treatment as this may permanently damage the internal sensor and void your warranty.
* Avoid shaking, dropping or otherwise shocking the scale. This is a precision instrument and MUST BE HANDLED WITH
EXTREME CARE.
* Only operate the scale on a stable, vibration free surface.
IMPORTANT:
Do not operate near cell phones, radios, computers, or
any other electronic device.
.** These electronic scale are precision instruments. Do not operate near an in-use cell phone, cordless phone, radio, computer or
other electronic device. These devices emit RF and can cause unstable scale readings. If your scale ever performs poorly, try
moving the scale to a different room or location. This is a very precise scale - the display may seem to wander or jump when
weighing. This is due to air currents or vibrations. Stable weighing is achieved when the display remains fixed for 3 seconds.
OPERATION_____________________________________________
Battery Operation:
1) Three #357 button batteries are required.
2) To install batteries:
a) Release the battery cover by sliding out-wards.
b) Place batteries into battery compartment aligned correctly.
c) Replace battery cover.
DO NOT USE EXCESSIVE FORCE & DO NOT PRESS ON THE TRAY!!!
3) The scale is now ready for battery operation.
(Advanced users only) CALIBRATION______________________________
IMPORTANT: This scale was professionally factory calibrated before shipment and does NOT need to be recalibrated by the end
user. However, if you wish to recalibrate your scale we provide these instructions for calibration:
Repeat calibration if the scale ever
shows Out2. Incorrect calibration can occur if you do not follow the steps exactly. If your scale does not perform accurately,
please try replacing your batteries before you calibrate. You will need a 100gram weight to calibrate this scale.
NOTE: if you do not
have access to a 100g weight you can purchase one at your local store or in emergency situations you can use 100g of coins or
weights (ie 20 US Nickels = 100g) as a 100g weight
..
1)
Turn the scale OFF and Place the it on a Flat, very stable surface
(Be certain the scale is OFF)
2)
Press and hold the
key for 10 seconds until a random large
number appears on the display - then release the key.
3)
Press the
key again, the display will show 2Ero and then
100.0
4)
Gently place a 100 gram weight on the scale and wait 3 seconds.
5)
Press the
key. The display will show CAL and then PASS,
calibration is complete. Remove the weight, then Press and hold the
key for 5 seconds to turn the scale
off.
NOTE:
if after calibration your scale does not read accurately, this indicates
calibration error and the calibration process should be repeated more slowly.
Please calibrate on a very stable flat surface
INACCURACY / ERROR___________________________________
The primary reasons for inaccuracy or malfunction are low batteries, incorrect calibration, overload or operating on an unstable
surface. Please keep this in mind and maintain and operate your scale properly. The scale is a precise instrument and must be
handled with the upmost care and caution.
