Cooper Instruments & Systems WTM 502 Wire Tension Meter - Manual (Page 11)

Reso Press the Reso softkey and you are prompted to enter a display, or count-by, resolution.
Choose from Low, Medium or High.
Low resolution provides the best stability and makes the display easiest to read. High
resolution provides the finest graduations, but sees greater drift from wire creep and non-
repeatability. If the reading is decreasing over time or differing between measurements
on the same line, lowering the resolution will reduce these effects.

• Enable lbf – Enable of disable the pound-force unit of measure.
• Enable kgf – Enable or disable the kilogram-force unit of measure.
• Enable N – Enable or disable the N unit of measure.
• Enable CUST1 – Enable or disable the Cust1 unit of measure.

Off Press this softkey to enable or disable the auto-shutdown. If you enable this function you
are prompted to set a period of time in minutes. Next, press the Enter softkey to accept
this value. You are then asked to set the shutdown type; Fixed, No Load, or No Change.
These are described below;
Fixed – The unit will shutdown after the set number of minutes no matter what happens.
No Load – The unit will shutdown after the set number of minutes only if there is no load on
the unit. This prevents shutdown in the middle of line tensioning.
No Change – The unit will shutdown if there has been no keypad activity or change in
tension after the set number of minutes.
ChPwd Press this key and you are prompted to enter a new password to access the
configuration menus. Use the softkeys to scroll in a new password and press the Enter
softkey to accept it.
Default Configuration password is 0. If a new password is lost or forgotten, contact Cooper
Instruments.
Reset Press this key and you are asked if you wish to reset the system. Press the Yes softkey
only if you want to continue. Press the No softkey to abort this and return to the previous
screen.
4.0 CHANGING SHEAVES
As you use the WTM 502 on different diameter cables you must change to the correct sheave size. To
change sheaves, remove the hex head screws pointed out in Figure 7 below. Replace the sheaves with
the correct letter sheave and reinsert the screws and tighten.
Insure sheaves installed agree with sheaves noted in the Wire calibration.
