Uf Pump; Conductivity - Fresenius Medical Care 2008k2 Manual

Shock Hazard: Do not operate the machine if the resistance is greater than
0.2 ohm. A shock hazard to operators and patients could exist.
7. With a digital multimeter, measure the resistance between the round
(ground) pin on the power plug and the redundant ground terminal on the
machine (See Figure 3, pg. 9). Verify that the resistance is less than or
equal to 0.2 ohm. If the value is above 0.2 ohm, measure the internal
resistance of your meter by shorting the leads together, then subtract this
value from the resistance measured between the power plug ground pin and
the redundant ground terminal on the machine to obtain the true ground
resistance.
8. Record the measured value on either the Six (6) Month Preventive
Maintenance Checklist or the Annual/4000 Hour Preventive Maintenance
Checklist depending upon which is being performed.
9. Perform the electrical safety checks required by local codes, facility
procedure and the Joint Commission on Accreditation of Healthcare
Organizations.

UF PUMP

Calibrate the UF Pump Volume (Refer to the 2008K
number 508137.)
Record the measured value on the Six (6) Month Preventive Maintenance Checklist.
2.6

CONDUCTIVITY

Verify that the dialysate conductivity measured by the internal cell in the machine
agrees with an external conductivity meter within 0.1mS/cm as follows:
1. Connect an external conductivity meter to the dialysate lines.
2. With the machine in Dialysis Mode and flow ON, compare the value shown
on the external conductivity meter with the conductivity shown on the
Display screen. They must be within 0.1mS/cm of each other.
3. Record the measured value on either the Six (6) Month Preventive
Maintenance Checklist or the Annual/4000 Hour Preventive Maintenance
Checklist depending upon which is being performed.
