Page 2: Specifications
With the DS-220, you can measure weight or liquid volume in both metric and English units, in addition to using it as a parts counter. The DS-220 is also programmable, and has a built in alarm to indicate a programmed threshold has been exceeded. Attaching the DS-220 to the CM- 500 Charging Module (optional, extra) allows automatic refrigerant charging for A/C systems. -

Page 6: Quick Start
DS-220 User’s Guide Quick Start To operate the DS-220 as a basic weigh scale, perform the following steps: Setup 1. Unpack the scale as described in the “Unpacking the DS-220” section below. 2. Install the batteries into the control box as described in the “Battery Installation” section below. - Page 7 8. To conserve battery life, the DS-220 will turn itself off after 30 minutes of inactivity, unless it is currently running a program (see Programming section). The last state of the DS-220 will be restored upon power-up.

BE USED FOR AN EXTENDED PERIOD OF TIME. Resolution The resolution (minimum incremental weight or volume) that can be displayed by the DS-220 can be adjusted to make the display easier to read. Unstable loads or high winds can cause the display to fluctuate erratically. -
Page 9: Measuring Volume
If the weight applied to the weighing platform exceeds the maximum capacity of the DS-220 (100 kg), a single “1” will be shown on the left side of the display. To prevent damage to the DS-220, immediately remove the weight from the platform. - Page 10 It is possible to determine the specific gravity of a liquid if you already know its volume. Using a graduated container appropriate for the liquid in question, perform the following steps: 1. Ensure the DS-220 is in VOLUME SPECIFIC GRAVITY MODE (refer to the Quick Start section).
- Page 11 . The display will now show the number of items on the platform. The DS-220 is now trained to recognize the weight of a single object as one count. This setting will be remembered until it is trained again. Note that can be used at any time while counting to “zero-out”...

Page 12: Hold Mode
To program the alarm, perform the following steps: 1. Set up the DS-220 in the desired weigh mode, units, and resolution as described in the Quick Start Setup section above. 2. If measuring decreasing weight, place the objects or container with the objects or material that will be removed on the weighing platform. - Page 13 The DS-220’s Tank Capacity Mode allows a continuous display of the percentage of material remaining in a tank. In order to compute the percentage accurately, the DS-220 must be trained to know the weights of an empty and full tank. To train the DS-220 Tank Capacity Mode, perform the following steps: Tank Capacity Mode Training 1.
- Page 14 Turning the Tank Capacity Mode On without Re-training The Tank Capacity Mode can be turned back on without retraining. The DS-220 will remember the previous 0% and 100% set points until the unit is re-trained as above. To turn the Tank Capacity Mode on without re-training, perform the following steps: 1.

Page 15: Battery Level Indicator
At this point, it is necessary to replace the batteries (refer to the Battery Installation section above). If the battery power drops to the point where the DS-220 can no longer function accurately, the alarm will beep 20 times and the power will turn off automatically. When the batteries are replaced, and the scale is turned back on, the DS-220 will resume operation with all previous setting intact. - Page 16 . Otherwise, the calibration or calibration restore functions will not operate. Sound As delivered from the factory, the DS-220 beeps when turning on and when keys are pressed. This sound can be muted as follows: 1. Make sure the power is on.
- Page 17 This section deals with specific applications for which the DS-220 may be used. HVAC Service Because of its high stability and accuracy, the DS-220 is ideal for automotive, commercial, and residential A/C refrigerant charging and recovery. Its high resolution also allows accurate critical charging of small refrigeration systems such as commercial freezers.
