level 1 System 1000 - Page 23

NOTE: Use of the TCW requires a digital thermometer NIST traceable and accurate to
within 0.1°C.
Required probe size:
0.099" OD maximum (0.25 cm)
0.50" - 1.50" long (1.27 - 3.81cm)
A short procedure to verify the displayed circulating water bath temperature is as
follows:
1. Install TCW in machine in normal heat exchanger position (Socket Fs 182)
and install a test filter assembly at holder (#3).
2. Turn the machine on and allow to warm up for 20 minutes. Insert
thermometer probe fully into well and allow display to stabilize. Compare
temperatures.
3. The System 1000 display will be within 0.3°C of the thermometer display on a
correctly calibrated unit.
Examples:
a. If the thermometer reads 41.4°C and the System 1000 is within the range
_of41.1°C - 41.7°C, performance is acceptable.
b. If the thermometer reads 42.0°C and the System 1000 is within the range of
41.7°C - 42.3°C, performance is acceptable.
NOTE: If the system does not conform to within these specifications, it should
be returned to SIMS Level 1 or an authorized distributor of SIMS Level 1 for
service.
3. D-SERIES CALIBRATION THERMOMETER (“TempCheck”).
Available from SIMS Level 1, the TempCheck device may also be used to test
performance and confirm proper calibration of the water bath temperature.
(Product Code # DSTA-40, part # 8001040) |
The D-series TempCheck device accurately verifies the temperature of the
System 1000 circulating water bath. It plugs into the auxiliary outlet on the
bottom of the H-1000 (See Figure 6) and does not require a separate NIST
traceable digital thermometer for operation.
