vetek OCS-S1 High Resolution Digital Crane Scale
Safety Guide
For good performance and precise measurement, be careful with daily operation and maintenance.
- Do NOT overload scale. This will damage loadcell and void warranty.
- Do NOT leave load hung on the scale for long. This will decrease scale’s accuracy and shorten loadcell’s life.
- Inspect shackle and hook before using. Check clips, pins and screws regularly.
- Check battery frequently. When scale runs out of power, replace the dead batteries with new ones.
- Rotate load rather than scale if needed.
- Do NOT use scale under thunder or rain.
- Hang scale on shelf in dry and well-ventilated room. Do NOT place scale on the ground directly.
- Do NOT attempt to repair scale yourself. Contact your local representative.

Operations
Power On/Off
- Long press
to power-on scale. Scale perform initialization and power-on test
, shows twice, then capacity 
shows, battery life percentage
shows, weight detection 
shows and then auto zero. - For information about Auto-Zero, refer to Scale Configuration in Technical Manual.
- Long press or
to power-off scale. Battery life percentage shows, off message 
shows, and then cut off power. - When 3 batteries voltage is lower than 3.2V, scale will auto power-off itself. Please replace the dead batteries with new ones.
Zero
- Long press
, or press
, to zero. ZERO shows. - If load is in motion, or tared, or out of Manual-Zero Range, shows.
- For information about Manual-Zero Range, refer to Scale Configuration in Technical Manual.
Tare In/Out
- In gross mode, press , or press
, to tare in. TARE shows. - If load is in motion, or negative, or out of Tare Range,
shows. - Tare will reduce the apparent overload range of scale. For example, if a 500*0.2kg scale has a 100kg container as its tare, the scale will overload at a new weight of 401.8kg (500 – 100 + additional 9 divisions).
- In net mode, press , or press , to tare out. TARE disappears.
Lock/Unlock
- Press
or
to lock screen. HOLD shows. - Press or again to unlock screen. HOLD disappears.
Accumulate
- Press
to accumulate current weight. 
shows, indicating weight is accumulated. Scale uses displayed weight, so gross or net weight is added into the same accumulator.- If load is in motion, or negative, or does not return to zero before, shows.
View
- Press
to enter View mode. - Display flashes accumulated weight.
- Press or to view high 5-digit or low 5-digit.
- Press or to exit View mode.
Delete Last Weight
- Press
to delete last accumulated weight. 
shows, indicating last accumulated weight is deleted. Delete function only deletes the last weight.- If last accumulated weight has been deleted, shows.
Clear All Weight
- Press
first and then press to clear all accumulated weight. 
shows, indicating all weight is cleared.
Unit Switch
- Long press or press , to switch unit in between kg, lb, and User Unit.
- When unit is kg,
shows. When unit is lb, 
shows. - For more information about User Unit, refer to Scale Configuration in Technical Manual.
User Setup
- Press first and then press or to enter User Setup menu.
shows.
Auto-Off Timing
- Press or to enter Auto-Off Timing. shows.
- Press or press or , to change timing value.
- Auto-Off Timing can be set to:0 (disabled),5 (5min),10 (10min),15 (15min),30 (30min),60 (60min). It is disabled by default.
- Auto-Off function maximizes scale’s battery life against people’s carelessness not to power off scale when it’s not working.
- Auto-Off starts countdown timer when there’s no action or load is stable. Any key pressing or motion in load restarts countdown timer.
Display Brightness
- Press or to enter Display Brightness.
shows. - Press or press or , to change brightness value.
- Display Brightness can be set to: (disabled),1 (dim),2 (normal),3 (bright).
- Dim display brightness saves battery power dramatically.
Idle Mode Timing
- Press or to enter Idle Mode Timing.
shows. - Press or press or , to change timing value.
- Idle Mode Timing can be set to: 0(disabled),5 (5sec),10 (10sec),15 (15sec),30 (30sec),60 (60sec). It is 30sec by default.
- To maximize battery life, scale automatically enters Idle Mode, when there’s no action or the load is stable. In Idle Mode, scale works in low-power consumption status. Any key pressing or motion in load wakes up scale from Idle Mode.
- Press or to exit User Setup.
Battery Maintenance
To maximize battery life, please note the following battery maintenance guide.
- This scale is powered by a 4 AA 1.5V batteries.
- Battery houses at the rear of scale can be opened by screwing off screws.
- Depending on display brightness and idle mode setting, normally, battery works over 25 hours.
- In order to conserve battery life, enable Auto-Off and Idle Mode, dim display brightness.
- When 4 batteries voltage is lower than 3.5V, scale will auto power-off itself. Please replace the dead batteries with new ones.
